Manufacturer: Swift Bullet Company 277
Swift A-Frame bullets combine soft point expansion with full metal jacket penetration. A leading core with a soft point initiates expansion, while a protected core in the rear retains mass and provides deep penetration.
Muzzle loader and heavy revolver A-Frame bullets are one in the same. Both initiate expansion at 950 feet per second, expand to .65x their original caliber, and maintain 97% of their weight. They are virtually indestructible at velocities in excess of 3000 feet per second.
