HSM/Hunting Shack GameKing Features The HSM/Hunting Shack GameKing load is built around the time-honored Sierra GameKing spitzer boat tail bullet a design long respected among hunters for its accuracy and consistent terminal performance. At 117 grains the bullet is matched specifically to the .25 WSSM case to maximize the pairing s potential for both accuracy and downrange performance. HSM precisely matches each caliber s individual components to its corresponding GameKing bullet a level of attention that gives the ammunition a handloaded feel while still coming out of a factory box. A muzzle velocity of 2874 feet per second and 2146 foot pounds of energy give this load solid reach and stopping power on game. Each round uses a reloadable brass case with a boxer primer allowing handloaders to recover and reuse components after a hunt or range session. Manufactured in the USA HSM holds its ammunition to consistent quality standards that hunters have come to rely on across its GameKing lineup. The 20 round box size gives hunters enough rounds for both practice and an actual hunt without excess. For hunters running a .25 WSSM rifle who want proven Sierra bullet performance in a factory load HSM/Hunting Shack GameKing ammunition is available for sale at GrabAGun.
