HSM .300 WSM ammunition (part no. 300WSM-41-N) loads a 180-grain Sierra GameKing Spitzer Boat Tail for hunters who want dependable performance in the field. HSM hand-loads short production runs using premium bullets from Hornady, Sierra, and Berger rather than mass-producing generic projectiles. The boat tail profile holds velocity downrange while the tapered jacket delivers controlled expansion on game. Cased and 20 to a box, it is built to feed reliably through bolt guns and semi-autos chambered for the cartridge. In our rifle ammunition lineup, this .300 WSM loading is a dependable choice worth adding to the cart.
