Swift A-Frame Heavy Rifle Bullets .458 cal .458" 400 gr AFSS 50/ct

The Swift A-Frame Heavy Rifle Bullets .458 cal .458" 400 gr AFSS are purpose-built for large-caliber hunters and precision rifle shooters who demand terminal performance in dangerous game and extended-range hunting applications. These bullets represent a proven solution for shooters working with .458 Winchester Magnum, .458 Lott, and similar big-bore platforms where controlled expansion and deep penetration are non-negotiable. Swift's A-Frame design has earned respect across professional hunting and military marksmanship communities for its consistent, predictable behavior downrange.

The 400-grain A-Frame construction features Swift's signature dual-core bonding process: a pure lead core in the front section for progressive deformation, coupled with a steel-reinforced rear core that maintains weight retention and structural integrity through heavy bone and thick hide. This architecture delivers expansion ratios of 1.5 to 2 times the original diameter while retaining 90–95% of bullet weight, ensuring adequate penetration for vital zone work on large African and North American game. The flat-nose soft-point (AFSS) profile enhances velocity stability in flight and provides additional contact surface upon impact, a critical advantage when engaging targets at distance or at marginal velocity thresholds.

Professional hunters, outfitters, and military/law enforcement riflemen working with .458-caliber platforms will recognize the value of Swift's manufacturing consistency and quality control—these bullets require minimal sorting and deliver the precision needed for handloads that group tight and shoot true. The 50-round box format supports both professional cartridge development and seasoned reloaders building backup or alternate loads. Shooters should verify bullet fit in their specific magazine system and confirm load data through published reloading references before deployment; the A-Frame's robust construction tolerates moderate velocity variations, but maximum powder charges and velocity windows remain critical for optimal terminal ballistics.
