Please refer to product specs. below 4 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. Accuracy BRENNEKE USA Special Forces (SFM) BRENNEKE USA SFM 5-shot, 1.65 inch group fired at 50 yards from bench.

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. 11
