The Hornady Superformance .338 Win Mag 200 gr SST 20 rounds box (Hornady part no. 82223) is .338 Winchester Magnum ammunition loaded with a 200-grain SST bullet. Hornady’s published figures from a 24-inch test barrel show 3,030 fps and 4,076 ft-lb at the muzzle, and 2,071 fps with 1,904 ft-lb at 500 yards. Superformance uses progressive propellants that Hornady says add 100 to 200 fps over conventional ammunition without extra chamber pressure, recoil or muzzle blast. The bullet is Hornady’s SST, loaded here at 200 grains in a Superformance round. It suits shooters who want the extra velocity of a Superformance load from a standard 20-round box for their .338 Winchester Magnum rifle.
