A Note from the President . . .
These days having the label “Prepper,” “Survivalist,” or the like, applied to you by the
media puts you on the very fringe of society and somehow makes you seem selfish,
evil and quite possibly off the deep end.
I will agree that some people let their paranoia get a bit out of control, but I also do
like the saying “Just because I’m paranoid, doesn’t mean they AREN’T out to get me!”
They take the preparedness thing to obsessive/excessive levels and invent terrible
scenarios in their minds which can make them worried and physically sick. I personally
think that being prepared is a core component of American life and freedom.
Properly positioned, it is a mind-set of self-reliance, while retaining compassion for
others less prepared or fortunate. I personally filter my preparedness with a dependence
on the Lord Jesus, knowing that my days are numbered and his to control, and that there
is a greater plan for my life than I can possibly know.
Thus the balance for me is weighing the knowledge I have of the world and world
conditions, my Boy Scout training and personal bent on one side of the equation and
my faith in the Lord on the other side. This provides what I believe to be Biblical
balance in my life. This also protects me from being panicked by every rumor or tremor
in society.
The Bible clearly teaches that we should be “Wise as serpents and innocent as doves.”
My understanding of this principle is that we should be aware and prepared for
anything we clearly perceive as a threat, yet not become evil or tip over into the dark
side protecting ourselves from every real or imagined threat.
In the Old Testament, Joseph was given a vision of seven fat years of productivity and
seven lean years of famine. His belief and action (an important set of words), led the
Pharaoh and the nation to store up a huge surplus in the “fat years.” This not only saved
them through the lean years of famine but also made the kingdom rich as the people
and nations from around the known world had to purchase food from Egypt.
This history provides us knowledge in many areas, including balancing our personal
budgets and saving for the future. I use this teaching and technique in my personal
finances and that of our businesses. For example, when prices are low on a product
such as a type of ammunition, I am a buyer and will inventory more than I need at the
moment. When the supplies dry up and a panic ensues, I can calmly stand aside,
letting others pay exorbitant prices or go lacking. The same approach should apply to
saving money, buying property, or even “prepping” and storing some food or other
commodities.

Jack’s Corner
Jack Landis is AGI Technical Services Manager, GCA Connection and GunTech Editor
This month begins a
change in the layout of this
magazine. As you all know,
for eight years (Happy
Eighth Anniversary
GunTech!!) we’ve taken up
a page or four, depending
on whether it is the SHOT Show issue or the October
Christmas Buyers Guide, with our Program Guide. It is that
long because we go into a fair amount of detail about the
contents of each segment of the video.
Add the verbiage and usually a picture and we end up
using more space than it probably warrants, I mean you
are going to watch the segments anyway, right? And,
we’ve been getting requests to add to the amount of gun
related content, i.e. articles, questions, tips, and such.
Therefore, we are going to drop the Program Guide and go
with the shorter "What's in this month's issue." We’ll still
have a picture if appropriate, but the description will
shorten up to about one sentence. That should cut the size
by at least a half. Let me know what you think.
The end of this month marks the beginning of a slightly
less frantic part of the year for The Boss and I. May
through mid-November have a few less commitments and
trips than Thanksgiving through the end of April. The
last/first part of the year has a pair of GSSF Glock pistol
matches, the Thanksgiving trip to Steelhead on the
Klamath, Christmas, New Years, a week of SHOT, another
week of NRA, a few trips to Napa and round that out with
a few trips to northern Nevada for wife’s family business.
You can see how a run-down old guy might get just a
touch frazzled . . . but then we’re not talking about
Mr. Kelly, we’re talking about me. And even for one as
youthful and vigorous as I, the schedule can get just a
might hectic.
I’ll be relaxing on my early June Ground Squirrel Safari to
Susanville this year while trying out my latest project. This
is a .17 Ackley Hornet in a T/C Carbine. I’ve had the gun
done for a few (10!) years, cases formed and components
on hand, BUT, until the past couple of years I have not had
convenient access to a private range to do load
4
development. Imagine, if you will, trying to do load
development on a public range with ½ hourly line breaks,
nowhere out of the wind to load cartridges (powder scale
readings are a might erratic in the wind or in the back of
your car). Also, lots of people stop by to ask questions or
offer their own invaluable advice on a subject they
obviously know nothing about. Just because I get paid for
that very thing doesn’t make me like it better when
subjected to it myself.
All that being said, I finally got around to doing some
loading and shooting with the gun. The barrel was made
by Fred Smith of Bullberry Barrels many years ago. It is a
24" full diameter bull barrel in chrome moly. I have a half
dozen of his barrels and they are all tack drivers. The one
in .17 HMR was used by my daughter Jeanne to kill a
rockchuck from a truck window at about 200 yards when
she was about 14 or so. Oh Baby! The picture of her
shooting it was the desktop of my office computer until
just a few years ago. Some dads have pictures of their
daughters at their proms or graduations, but Hey!, I’m a
gun guy.
The .17 Ackley Hornet is just the .22 Ackley Hornet
necked down to 17 caliber. For those of you fresh to the
reloading game, an Ackley Improved cartridge is a
standard cartridge, say a .30/30 Winchester, with the body
taper reduced as much as possible while still getting easy
extraction, the shoulder moved forward, and the shoulder
angle sharpened to 30 or 40 degrees. When the Ackley
chamber is properly cut, you can shoot factory ammo, in
this case .30/30 Winchester, in the Ackley Improved
chamber.
Bull Barrel dimensions
This also fireforms the factory brass to the Ackley
dimensions. The Ackley brass holds somewhat more
powder than the original factory case and the powder is
thought to burn more efficiently in the straight wall, sharp
shouldered case. Ackley proved that the straight wall
shape also reduced thrust against the bolt/breech face.
If you want to get into Wildcatting, the Ackley Improved
cartridges are the easiest way to get started. The fact that
you can shoot factory ammo is a big advantage if you run
Note from the President continued . . .
The question is; will you be in a position to be benevolent or
will you be locked out, begging and suffering? The same
applies to getting the knowledge you need NOW rather
than later. It may not be available then or your need to apply
it might be instantaneous. Not having it could prove disastrous. A further benefit when it comes to gunsmithing, this is
also a highly “barter-able” trade. Try trading “therapy
sessions” in a crisis for food, ammo, repairs, or the like.
Good luck with that!!

body, shorter neck, and sharper shoulder angle on the Ackley.
out of or, as has happened, your reloaded ammo gets left
at home.
The .17 Ackley Hornet is a VERY efficient little cartridge.
Like most small cartridges you get more velocity than you
would expect from a small amount of powder. The .17
Ackley has always had the reputation of being able to
move the 25 grain Hornady at 3,500 FPS. I don’t know
about that as I’ve not loaded any Hornet cases with the 25
grain bullet, but I’m here to tell you that 12.0 grains of
Accurate Arms AA-1680 will cause the 20 grainer to move
out smartly at 3,550 FPS with no pressure signs. That’s
enough sheer velocity to absolutely inflate a ground
squirrel to a cloud of red mist. Impressive!
The .17 Ackley Hornet IS NOT the Hornady .17 Hornet.
Do not attempt to load the Ackley in the Hornady
chamber, evil things will occur. I believe (DO NOT TRY
THIS AT HOME!) that you should be able to safely load
the Hornady in an Ackley chamber without dire results, but
I have not yet tried it. Since the cartridges headspace on
the rim, the slightly smaller dimensioned Hornady would
headspace properly.
Fred Zeglin has an article on Wildcatting in this issue.
I hope you caught him on this month’s GCA Live webcast.

around . . . Til next month, break some new ground

Life's truths . . .
It is a mistake to allow any mechanical object to
realize that you are in a hurry. One theory is there
is a special circuit in machines called a
"critical detector" which senses the operator's
emotional state in terms of how desperate he or
she is to use the machine. The "critical detector"
then creates a malfunction proportional to the
desperation of the operator. Threatening the
machine with violence only aggravates the
situation. Likewise, attempts to use another
machine may cause it to also malfunction. They
belong to the same union. Keep cool and say nice
things to the machine, nothing else works.

How can Wildcatting
make you self-reliant?
By Fred Zeglin; AGI Instructor, Cartridge Designer and Author.
Lassen College Gunsmithing Graduate
Wildcatting teaches you many things; chief among them would be a good
understanding of headspace and pressure, both topics of primary
importance in reloading. When you understand headspace as it relates to
reloading dies, guns, and ammunition you can resolve many problems that
perplex the average shooter. Understanding pressure will help you select
appropriate components for both wildcat and factory designed cartridges.
I have a book in my personal library, “The Home Guide to Cartridge Conversion” by George C. Nonte, Jr. This book
offers suggestions with each cartridge described as to how you might make brass. It covers cartridges in Metric as well
as U.S. designs. This book has become collectible but you really do not need the book to figure out these
relationships. All you really need are some measuring tools and an understanding of how far brass can stretch when
you’re reforming it.
The first cartridge I ever formed was a .25-06 from .30-06. I had no idea what I was doing but I had read all about the
process. I was expecting the sizing down to be a problem because of all the articles I had read. Turns out it’s no big
deal. After all I was really only working the neck of the case. But that experience took the mystery out of the process
for me and the next time I needed to form brass, I just dove in. You might wreck a few pieces of brass but that’s how
you learn.
As you learn to form brass for your wildcats, you’re also learning how to adapt and make use of what is available to
you. Of course, that is not normally the concern when you’re wildcatting. Rather we are trying to solve ballistic
problems, adapt a cartridge for a new firearm or just have a little fun. But this experience can easily be utilized to get
by when supplies are hard to locate.
Let’s say times are hard. You have a barrel but no reamer. If you dig into wildcatting you can learn how to make your
own chamber reamers. On top of that you can make reamers for reloading dies. Sometimes knowledge and scraps of
material are available when there is little or no money to be had or wasted. Ask Grandpa if he ever had to make do
with what was on hand.
I can hear guys saying, “But if times are hard I won’t be able to get tool steel to make dies…” Guess what? Modern
chromoly (blue) barrels are nearly all made from either 4140 or 4150, both tool steels that can be hardened for dies.
So, a shot-out old barrel might be a good source of die material. This material would then be oil quenched
when hardening.
Keep a few sticks of oil hardening drill rod around the shop. You can easily turn
out a reamer for any cartridge you design or even for any existing cartridge.
This is how gunsmiths in days gone by acquired reamers before
there were companies they could order from. On
occasion, time is more important than money, so
being able to make a reamer in-house can save
weeks of waiting.
Most of the times I used this trick were when I needed a special neck or throating reamer and
simply could not wait for one to arrive from the reamer maker.
6
A cannon reamer
for a chamber neck
is shown here.
The most common name for these reamers are “half reamers” or “cannon reamers.” They are easy to make. Simply
turn a blank on the lathe in the shape and dimensions you need for your chamber or die. Then you can file,
grind, or mill away half the profile. You will need to build in a pilot and a drive end. I normally
harden them at this point and then grind relief into the reamer so it will actually
cut and not drag or gall the chamber. A little hand sharpening
for good measure and you have a reamer.
The picture to the right shows a cannon

reamer for the full chamber. Looking at the
flat, you might consider this a single tooth cutter. The picture below shows the reamer in profile so you can get a
better idea of the relief grinds. Take a look at any professionally made reamer in your collection and copy the reliefs.
It’s not difficult. Are these tools beautiful? Not really, but they work and in a pinch can be a real life saver. Wildcatters
who learn to make their own tools will be able to
Profile of a cannon reamer for the full chamber
test more ideas simply because of the
saved time and money.
Reloaders who wish to be self reliant should also invest in a “Vickerman” style bullet seating die
(http://vickermandies.com). These dies are known as inline style bullet seaters. In their various forms they are nearly
always more accurate than conventional seaters that come with a die set. One inline die can be used for just about any
cartridge simply by changing out the inserts. Naturally, this saves money over buying a complete die for every caliber
and is super useful to the wildcatter. The best forms of this die are not cartridge specific but rather work on the neck
and bullet diameter.
Ponsness/Warren Cal Die
There are numerous die makers offering variations on the inline bullet seater. Some are specific to
the cartridge, which of course is not the version we are looking for here. Meacham,
Ponsness/Warren and Vickerman are all versions that work on the case mouth. This
allows you to use the caliber insert for any cartridge of that caliber without
regard to the shape of the case.
In the Ponsness/Warren die pictured here the caliber
insert is sitting in the window of the die. This
insert floats up and down in the die during
the seating process. This type of insert
Ponsness/Warren die
rests on the case mouth while holding the
bullet aligned with the case for easy and
accurate seating. The most important feature of inline dies like this is the ability to change from one caliber to another
by changing the insert. Those of you who have done any work on a lathe will immediately recognize that these inserts
can easily be turned out in a few minutes for any caliber, thus, adding to your self-reliant list of skills and abilities.
Now that I have shown you some quick and cheap ways to make tools and
dies, let me show you one other way to make reloading dies that allows you
to skip the need for a reamer at all.
Left: The beveled end of the insert is
where the case mouth centers up on the bullet.
Right: The top of the insert. When you drop
the bullet in the window, it centers up in the
insert, ready to be seated.
I use the body from the inline seater pictured above to hold 5/8” diameter
sizing dies. I use these primarily to prove out ideas and test new wildcat
designs. They are not as good as a conventional sizing die but they are
expedient, meaning I can be forming brass in less than an hour in most cases.
Heavy forming of large diameter cases is not recommended in these 5/8”
inserts. Even so, they could be used for proof of concept.
Taking 5/8” drill rod or 4140 tool steel, I cut it to length and face it
for the desired cartridge. Normally I make these dies in two pieces,
7
one for the body and one for the shoulder and neck.
By doing so, it makes fabricating to body and shoulder
angles easy without need for a one piece reamer. On the
lathe, I use a boring bar to cut whatever taper I may
need for the body of the case. Utilizing the compound
on the lathe, you can set the angle you want for the
shoulder then ream or bore the neck diameter.
You can even make an insert for the neck only if all
you’re doing is sizing the neck. This is a really fast way
to test a new caliber.
Alignment of these two piece dies is not a problem.
I have used steps to interlock the pieces and I have used
beveled ends to make them self align. Both work and
neither is really necessary. The simplest form is to face
the two parts square, then when I form the first piece of
brass, I leave the jam nut that holds them in the die body
a tiny bit loose. The two parts naturally center up on the
brass. I then tighten up the jam nut before fully
extracting the newly formed case.
Every trick or ability you add to your bag of tricks makes
you better able to make a living, serve clients and survive
in good times or bad. The tips mentioned here are tried
and true, having been used by more than one generation
of gunsmiths. You need not reinvent the wheel. P.O.

any wildcat rifle he built. He picked up this habit for two
reasons. First, it meant extra income and second, his
client was assured of having dies that matched his
chamber correctly.
The “Taming Wildcats” video I did for AGI explains
more than just how to design a successful wildcat.
Even more important is the detailed information on how
to make your own chamber reamers and reloading dies.
This is nearly a lost art for today’s gunsmiths.
Check it out below.
Everything you ever wanted or needed to know to design
and build your own custom cartridge and reamer!
Taming Wildcats is taught by Custom Gunsmith Fred Zeglin, renowned cartridge
designer and builder of the well known Hawk series of cartridges. Fred will get you
on the road to a thorough understanding of Wildcats and Wildcatting, showing you
everything you need to know to do it yourself.
Over two hours in length, this course takes you smoothly from the dreamin’ up and
design phase through the actual case forming and chamber reaming stages. If you
can run a lathe, you will be able to make your own reamers after watching this
detailed course!! How to do ballistic research and the software programs that are
available to help you design your cartridge case are ALL covered.
You don’t have to be a master machinist or a tool and die maker to be able to turn out resizing/forming/chamber
reamers on the lathe. AND . . . Fred shows you why you don’t need an expensive tool post grinder. A bench grinder
with a good, squared edge, fine grinding wheel and some practice will, with Fred’s expert and easy to follow
guidance, enable you to turn out reamers that will equal anything you can buy - for a WHOLE lot less!!! Oh yeah, and
he shows you how to sharpen and heat treat them as well! $79.95 plus ship. Only $63.96 for GCA Silver Members!

THIS COURSE WILL SAVE YOU A LOT OF MONEY!!
Question of
the Month
Jack,
I got a Remington 48 in last week with one of the links stuck
between the action spring tube and the action spring follower.
Of course Remington redesigned to prevent this on the 11-87.
Do you know if an 11-87 action spring follower would work in
the model 48? If it would, I could TIG weld a "knob" on the
ends of the links, and file them to hook into the follower and this
problem would never come back. If not this solution, is there
another way to prevent this type of jam?
Gary
Gary,
Well, I have seen only one Remington Model 48 in my entire life.
Therefore I really didn’t feel competent to answer this question.
Hmm, let’s see, who might possibly know the answer to this
question? You know, someone who was already a gunsmith with
decades of experience when the gun made its debut in 1949?
Hey! I know, how about Himself, the venerable Bob Dunlap?
Yeah, sure, he would know. I forwarded this on the The Great
One and he replied as follows:
If the follower and tube are OK, just TIG weld the ends of the
link together and taper them slightly so they cannot get
between the follower and tube. Do not soften more than ¼" of
the ends of the links when welding.
Bob
Jack,
Man, I love that guy!
Thanks a bunch. What a simple fix. When you hear what Bob
comes up with, do you ever ask yourself, "Why didn't I think of
that?"
The gun now works great, and I'll bet this problem never comes
up on this gun again. As soon as I get some down time, I'm
going to do this to my own old 48.
Gary
Yeah Gary,
I ask myself that all the time, that’s why he’s The Great One.

Coming
Next Month
The month of May is traditionally when it starts to heat up
and things will definitely be heating up in the May issue of
GunTech!
Tavor TAR Bullpup Rifle from Jerusalem with Love
This month Gene visited the IWI factory in Israel and
checked out the new Tavor bullpup battle rifle. In the May
issue we take things to the next level when we conduct a
full bench and field evaluation of the Tavor to see just what
it’s made of!
John Bush will be back in “The War Room” and this time he
is going to give you just a peek at the amazing world of
adaptors. Not sure just what that means? Then you’ll just
have to wait until next month to find out but trust us… if
John knows all about it, then it’s pretty darn interesting!
Gene is going to check out a “stock to end all stocks” (at
least that’s what KRG thinks!) and a belt-fed rifle you can
own! Meanwhile… Darrell, Jack and Keith will be reviewing
new products and Ken will be back at the workbench with
another great tip.
Speaking of tips… In “Tips for the Woodsman” Darrell will
shed some light on, well… lights! He will be showing you
several makes and models in order to give you a snapshot
of the current market when it comes to features,
performance, and cost.
Of course it wouldn’t be
GunTech without your Disassembly/
Reassembly Course would it!?
Chiappa MC 27
Fear not, we didn’t leave it out! In
fact, this month we will have another world’s first!
Ken will take you through the complete disassembly and
reassembly of the new Chiappa MC 27 pistol which we
JUST evaluated!!
You can see the May issue has a lot to get excited about, so
you may want to start making extra ice and turn up the air
conditioning now, just to keep from getting hot under the
collar over next month’s issue of . . . GunTech!

The Remington
760 Gamemaster
By Robert Dunn,
American Gunsmithing
Institute Master Gunsmithing
Course graduate, GCA
Member, AGI/GCA video
producer and cameraman.
I would like to start this article by saying
that my neighbors are the best folks on
this planet. They have literally helped
me survive the last several months of
my life. They have helped me with
everything from food to firewood to
simple friendship. One thing that we all
seem to have in common is a love for
firearms.
I spent some time over at my neighbors, Grant and Mapril,
and we laughed about the fact that we don't have too much
of a crime problem out this way because everyone knows
we are all “adequately” armed and protect one another.
With that being said we spent the morning talking about
firearms and they showed me some of their cherished guns.
I showed a particular interest in a Remington Model 760
and, without hesitation, Grant handed me a box of .30-06
cartridges and the rifle and told me about his favorite place
shoot on his land. Like I said,
I love my neighbors!
Anyway, the Remington Model 760 was introduced in 1952
and production ceased in 1981. That is a pretty good run.
During this time period Remington manufactured over one
million of these pump action rifles. The 760 replaced the
Model 141 and was replaced itself by the Model 7600. L.R.
Crittendon and William Gail, Jr. designed the Model 760.
The rifle has the classic Remington profile and looks great
topped with a scope. The receiver is made of steel and is
machined. The magazine is a removable box. The 760
utilizes a rotating bolt that has 14 interrupted thread type
lugs that lock into recesses in the barrel extension. The
locking system is very strong and thus safe in the case of an
overload, etc. The twin action bars allow the rifle to cycle
smooth and fast. The action bar lock also acts as the
10
disconnector on this firearm. The magazine holds four
cartridges.
When disassembling the 760, you can open the action and
put a punch in the holes in the action tube to break it loose
from the receiver. The action tube can then be unscrewed.
The action tube guard should have some play when the gun
is assembled so it does not push up on the barrel. The
barrel comes off the receiver by pulling it off. If it is tight,
slam the pump forward (bolt closed) a couple of times and it
will eventually come off. There is a part called the action
tube guard that prevents the barrel and the action tube
from hitting one another. Next, you can unlock the bolt from
the barrel and rotate the forearm and action bar around the
recoil lug to remove it from the barrel.
The barrel consists of the barrel itself, the barrel extension,
and the recoil lug (barrel bracket). The barrel extension
contains the locking recesses for the locking lugs of the
breech bolt. A special wrench can be made to unscrew the
barrel extension and the recoil lug can be driven off. If
you have to correct headspace, you can do a barrel set-back
by taking off the barrel extension and the recoil lug and
setting the barrel back as much as needed to correct the
headspace. It is easiest to face off the amount you need to
correct from the recoil lug. You also have to face off the end
of the barrel so the bolt will fit correctly. You must then use a
chambering reamer to adjust the headspace.
Most of the bolts snap into the action bar but some are
silver brazed in. The bolt utilizes a cam locked system and
the bolt head (breech bolt) is rotated/screwed into the
locked position by two cam pins in the bolt carrier. When
the bolt is locked up, the firing pin can reach the primer to
fire the gun. If it is not locked up, the firing pin cannot hit
the primer of the cartridge. The cam pins can be pushed
out of the bolt head to take the bolt apart. Headspace can
also be corrected by making two new cam pins out of 4140
alloy type steel that are hardened and drawn back to a
purple/blue color. The cam pins must fit very precisely in the
cam slot. This will take up some of the “slop” (or play) in the
bolt. Now, when the gun is closed the bolt head will rotate
farther, thus correcting the excessive headspace. These
Remington rifles do not develop excessive headspace very
often.
The action bar lock locks behind the action bar. This is what
keeps the gun locked up. The engagement angle of these
parts should be slightly positive. In most cases, this will
prevent problems associated with the shooter “squirreling.”
Bob Dunlap likes to see .010" to .020" clearance between
the action bar and the action bar lock when the gun is
closed and locked up. .040" will not hurt anything though,
and is actually Remington’s spec.
There is some play between the bolt head and the bolt
carrier. This play in the semi-automatic version of the rifle
will delay the unlocking of the gun enough to allow the
bullet to get past the gas orifice and move the action bars
back before the gun actually begins to unlock. The bullet
will have exited the barrel at this point too.
Here we can see the interrupted threads
on the bolt of the 760
This series of firearm is not the most accurate. The early
model’s barrels were held onto the flat front face of the
receiver by a nut screwed onto the end of the forearm tube,
against the barrel’s recoil lug. The barrel would tend to
wander from shot to shot and accuracy suffered. You can
3-point bed the receiver to the barrel to improve its
accuracy (like a three legged milking stool) so the point of
impact remains consistent. Make sure the forearm spacer
does not touch the barrel on the pump version of the gun.
The early guns tended to break stocks because they did not
have stock bearing plates. The stock bearing plate increases
the amount of surface area the stock has to bear against. To
prevent breakage and improve accuracy, glass bed the stock
to the stock bearing plate (this will lock the stock into the
receiver).
The auto version has a disconnector in the fire
control system. If the gun cycled but did not close, the
disconnector would be underneath the action bar and
pulling the trigger would not drop the
hammer. The pump actually works the
same way. The difference is the pump
gun’s action bar lock has a slightly
positive engagement angle with the
action bar and the auto gun’s
disconnector has negative engagement
with the action bar.
The trigger has two connectors on it
(one on the left and one in the center of
the trigger group). When you pull the
trigger, the connectors move forward
and the central connector bumps into
the sear, causing the top of the sear to
move rearward out of engagement with
the hammer…the gun fires. The spring
and plunger that power the hammer

Congratulations!
bump into the shelf on the disconnector and the trigger is disconnected.
The sear is free to catch the hammer again. If you are getting misfires,
you should check the length of the hammer’s power stroke. A longer
power stroke will impart more energy to the hammer to fire the primer.
The trigger and the connectors
are restricted parts, so work on
them carefully. The safety is a pin
that blocks the back of the trigger.
The engagement of the sear to
the hammer is conventional.
Bob Dunlap shows us the
Doing a trigger job would involve
trigger group from a 760 rifle
adjusting the hammer’s notch
rather than the sear. Altering the sear will change the sear’s position in
the gun and it might not reconnect. The engagement of the sear to the
hammer should be slightly positive. De-creeping the trigger may not
lighten the trigger pull much, but it will make the pull feel smoother.
The sear spring must have closed ends or it could fall off the sear and/or
trigger when the gun is cycling and then the gun will not cock.
To lighten the trigger pull, Remington will pound the sear spring to coil
bind it. This will make the spring weaker, thus lightening the pull. The
Dunlap method is to use a band sander to sand the coils of the sear
spring down and reduce its diameter. This will make it weaker and
lighten the trigger pull. The trigger pull should not be less than 4.5
pounds, anything less can be unsafe.
I am a big fan of the Remington 870 pump shotgun for a home defense
gun and I like the idea of including a 760 (chambered in .30-06) for
perimeter defense, as all of the same motor skills you train for the shotgun, transition to the rifle effortlessly.
I could use my Remington 700 bolt action rifle (also in .30-06) for even
further distances. While I'm on a roll, I might as well suggest a
Remington R1 1911 style pistol for up close and personal encounters.
I enjoyed shooting the 760 very much, though I am left handed and a
Monte Carlo comb on a right handed stock tends to tear my cheek up a
bit.
With a standard Remington butt stock, I would take this rifle with me
when I go hiking around home, as my home is also home to bears,
mountain lions, bobcats, and coyotes. I surely wouldn't mind using a 760
for a deer rifle, especially in .30-06. The pump action would be great for
quick follow up shots if needed.
There aren't too many firearms that I don't like, but after shooting the
760, this rifle has moved up a good few notches on my want list!

Congratulations to the 36 of you who took the time to email me
an answer to last month’s question. All 36 were correct that the
part is a Bolt Cam Pin for an AR system rifle/carbine/pistol.
Congratulations to all of you, although I thought there would
have been more of you, given the popularity of the gun involved. We also have
first time winners this month. 21 of you were right in that the systems designer
was Eugene Stoner. Dang you’re smart!
Apologies are in order - we missed this winner last month, Sorry Dr. Dev – Ed.
C-96 Movie Role Winner: Devin Southam!!! Last month’s winners are shown below.
OK, this month’s part is maybe almost as common as last month’s part, in that it exists in four
currently made models of the guns it lives in. With some minor variations it has been around for
~120 years. Can I make it any easier than that? Again, I want the exact name of the part that the
manufacturer uses for it, not “square metal thingy.” We’ll give the “Dang Your Smart” $20 credit
prize to winners who also know the designer’s first and last name.
You can call me with the answer ONLY if:
1. You do not have email access.
2. You call (800) 797-0867, ext.104 between 0800 - 1700 PST Monday - Friday.
3. If you get my voicemail, you leave your name, phone number, and guess.
The voicemail time stamps, so be CLEAR with the info.

NOBODY! HA!
We had several of you allege that Mr. Kelly, Himself, actually misidentified a few
handguns in one of his SHOT Show segments…Really?! Perhaps, in their excitement,
they failed to read the hi-lited sentence below. It is, by definition, impossible that he could
be wrong. Obviously the manufacturers of the guns involved somehow mis-stamped
those particular guns . . . That’s our story and we’re stickin’ to it!
Nobody caught those of us allowed fallibility in an error.
Jack is not quite perfect this month, and Ken, John, and Keith . . . well, seriously??
Gene, Bob, Darrell and Mz. Lenée are exempted from the ignominy they and AGI/GCA
would suffer in the extraordinarily miniscule possibility that they would actually err.
Good luck to all of you in your search this month. Remember, it’s worth $40 to catch
one of us, at least if I agree. Remember we’re not talking opinions here, opinions are
like noses, everyone is entitled to one. By “Dumb Statement” we mean a real,
unnoticed and uncorrected erroneous statement, i.e. saying hammer instead of
striker, Colt instead of Smith & Wesson, D/R instead of Bench & Field.
Don’t despair, keep looking and listening.
