Brownells 75th Anniversary - A Shooting Heritage

The Black Butterfly Premium .458 SOCOM round was created for target and or close quarters training 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 monsterous projectile 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 in 250, 500 and 1,000 count bags for reloading.
  • Manufactured with new Starline Brass, CCI Primers and CTX Lead Free frangible Bullets. Ammunition Comes packaged in a hard plastic clear Berry's MFG Box.

Disclaimer: The 458 SOCOM cartridge is not yet an approved SAAMI cartridge. This means there is currently no standard pressure, velocity performance or dimensional characteristics for the 458 SOCOM. If you experience any feeding or cycling issues, please contact your firearm manufacturer.
