HSM 338 Winchester Magnum 250gr Sierra GameKing Ammunition, 20-Round Box

HSM 338 Winchester Magnum ammunition (part no. 338MAG-17-N) loads the heavier 250-grain Sierra GameKing spitzer boat-tail bullet, giving hunters extra bullet mass for the biggest game the cartridge is called on to handle. HSM loads this ammunition on reloadable brass cases for hunters who want both factory reliability and the option to handload once the brass is fired. The heavier 250-grain weight trades a little velocity for additional penetration compared to the lighter 215-grain loading, favoring deep, straight-line penetration on the largest, heaviest-boned animals in North America. In rifle ammunition for 338 Winchester Magnum hunters, this is a heavy-bullet option for the biggest game.
