Black Butterfly, Premium, .458 SOCOM, 250 gr, Lead Free, GPM QUADRA-SHOCK HV STINGER NICKEL

This NON-FRANGIBLE round with a density similar to copper was created self defense and hunting applications. Due to the fact the projectile is lead free, it can also be used in lead free ranges and in states like California that are gradually phasing out lead projectiles.

This "Quadra-Shock" projectile is exclusively manufactured in this form for Black Butterfly Ammunition to be used in a .458 SOCOM platform. It was designed to give the shooter the maximum OAL possible which we feel dramatically increases its accuracy. The shape of this projectile also insures it will feed properly from any standard GI mag on the market.

This is an exclusive product manufactured by CTX to Black Butterfly Ammunition’s specifications.

This projectile is also offered to the public for reloading exclusively through

The average muzzle velocity is a screaming fast 2000 FPS.

We recommend this round for self defense and hunting applications.
