HSM/Hunting Shack GameKing Features The HSM/Hunting Shack GameKing line is built around the Sierra GameKing and Pro-Hunter bullet line bullets that have earned a reputation for accuracy and consistent expansion across decades of hunting use. In .257 Roberts HSM loads a 117 grain soft point bullet that is matched component by component to the cartridge a process the company says produces handload level precision from a factory box. The soft point design is built to expand reliably on impact delivering the terminal performance hunters expect from a mid weight big game bullet. Each load is assembled around the time tested .257 Roberts case a cartridge long favored for flat shooting accuracy on deer sized game. Every round uses reloadable brass casing with a boxer primer giving handloaders the option to reload spent cases after firing. The ammunition ships 20 rounds to a box a standard count that makes it easy to keep multiple boxes on hand for practice and hunting trips. HSM positions the GameKing line as a bridge between factory convenience and handload accuracy carefully matching bullet powder and primer for each individual caliber offered. For hunters chasing deer antelope or similar game with a .257 Roberts rifle this GameKing loading offers a dependable accurate option for sale at GrabAGun.
