BRENNEKE USA SLUGS
(Product Specs., Ballistic Data)
BRENNEKE USA SFM
Our 1 1/4 oz. Special Forces Short Magnum (SFM) load provides tactical performance for the law
enforcement officer who needs maximum penetration. Our SFM penetrates car doors, building materials
and windshield glass with ease while retaining plenty of residual energy and momentum to incapacitate
post-barrier targets. Its strength and efficient nose shape allows it the ability to defeat an engine block.
The 525 grain SFM provides extreme stopping power due to its higher ballistic coefficient and higher
downrange velocity. Like all Brenneke law enforcement slugs, the SFM wad remains attached in flight
which eliminates liability and the possibility of collateral damage (injury to innocent bystanders). Our SFM
can be accurately fired from both smoothbore and rifled barrels.

Ballistic Advantage:
Note the large frontal area, kinetic energy and momentum of the Brenneke USA Slug vs. the typical L.E. handgun rounds -- or
even the high-velocity .223 entry round. A high momentum value allows a projectile to penetrate both hard barriers and soft
targets. But a high momentum factor also allows a projectile to maintain a higher average terminal velocity during penetration. I.e.,
its low rate of deceleration and greater frontal area causes not only more tissue damage (and hemorrhage), but more nervous
system trauma which can stop a gun fight instantly. When a slug of this size and momentum traverses a living system, it halts
aggressive action.
