Swift A-Frame Heavy Rifle Bullets in .458 caliber, 400 grains (Swift part no. 454001), are built for handloaders who need controlled expansion and deep penetration on dangerous or heavy game. Swift’s A-Frame design uses a cross-member copper jacket coupled with a bonded front core, producing three key traits: controlled expansion, roughly 95 percent weight retention across velocities, and deep penetration. The bullet consists of a soft semi-spitzer lead nose that protects against felt recoil while still seated in the magazine, a tapered jacket around a pure lead core that controls expansion rate, and a wraparound jacket on the base. Swift positions this uncoated bullet to outperform competing designs on retained weight and penetration.
