Brownells 75th Anniversary - A Shooting Heritage

The Black Butterfly Premium .458 SOCOM round is intended for all large big game animals. This round is extremely accurate, shoot flats and defies cross winds due to its unique composition. This round utilizes the Nosler Projectile which includes the signature polymer tip to increase long range efficiency and protect against tip damage. This round is known to open at lower velocities and fully expand, leaving a large “mushroom” projectile.

Manufactured with new Starline Brass, CCI Primers and Nosler Ballistic Tip 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.
