Swift .323 A-Frame rifle bullets, 220 grains, A-Frame semi-spitzer, 50 per box. Hunters know the importance of weight retention for superior on-game performance. The Swift premium A-Frame construction and proprietary bonding technique insure 95%+ weight retention, even on large game with heavy bones. Because Swift bullets are virtually hand made, critical tolerances are held to exacting standards. Swift A-Frame performance is unmatched by other offerings: the tapered sidewalls of the upper chamber allows expansion to begin at relatively low velocity levels with progressively greater control achieved as the walls thicken until upset is completely stopped at the rigid A-Frame crossmember. Swift's exclusive proprietary bonding process holds jacket and core together during the tremendous mushrooming forces. Swift A-Frame bullets do not come apart. The protected rear core at the bottom of the bullet retains the needed weight and energy to drive the bullet deep, for the ultimate in game-anchoring performance.
