HSM .357 Magnum 158 Gr. Sierra Pro-Hunter Jacketed Hollow Cavity- Box of 50

HSM Ammunition has partnered with Sierra Bullets to develop an entire lineup of hunting ammunition featuring the time-honored Sierra GameKing/ProHunter bullets. Each caliber’s individual components have been precisely matched to each bullet to maximize their potential for accuracy and performance. So precisely matched that you may think HSM ProHunter’s are handloads rather than coming out of a factory box. Whatever your quarry, HSM has a ProHunter cartridge to suit your needs.

The traditional, flat base design of the Pro-Hunter has been skillfully blended with Sierra’s world-famous accuracy. The custom-tapered ProHunter jacket design helps assure maximum expansion, optimum weight retention and deep penetration for game-stopping, 1-shot performance. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.
