Does the “GameKing” moniker ring a bell? It should, Sierra “GameKing” bullets have earned superlative accolades for years. 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 GameKings are handloads rather than coming out of a factory box. Whatever your quarry, HSM has a GameKing cartridge to suit your needs.
