HSM/Hunting Shack GameKing Features The HSM/Hunting Shack GameKing line is built around the Sierra GameKing soft point bullet a projectile with decades of proven accuracy and expansion behind it. HSM matches each individual component in this .300 WSM load specifically to the 150 grain bullet from powder charge to primer selection so the ammunition performs with a consistency that factory loads rarely achieve. The 3100 feet per second rated velocity gives hunters a flat trajectory for longer range shots at big game while the soft point design ensures controlled expansion on impact. This attention to component matching is why HSM GameKing ammunition is often mistaken for careful handloads rather than factory production. Each box ships with 20 rounds of boxer primed reloadable brass cased ammunition giving handloaders the option to reload their fired brass after a day in the field. The brass cases and boxer primers are built to standard reloading specifications extending the value of every box well past the first firing. HSM s GameKing lineup covers a wide range of calibers each matched the same careful way so hunters can standardize on a trusted load across multiple rifles. This HSM GameKing .300 WSM load is available for sale at GrabAGun for hunters who demand handload-level precision from a box of factory ammunition.
