This 20-round box of Sellier & Bellot .300 Winchester Magnum 180gr SPCE ammunition (Sellier & Bellot part no. SB300B) is a 180-grain semi-jacketed soft point cutting edge load. The bullet is a cutting edge that locks the jacket and lead core together while producing a clean entrance wound and easy-to-follow blood trails. The cutting edge locks the jacket and lead core together, and Sellier & Bellot describes the bullet as appropriate for light to medium game. Sellier & Bellot publishes 2,936 fps at the muzzle and 3,446 ft-lb of muzzle energy, measured in a 23.5-inch test barrel. Those numbers belong to this 180-grain SPCE load only, which is what separates it from the other .300 Winchester Magnum boxes the maker sells.
