Hornady Superformance item 82223 is 338 Winchester Magnum loaded with a 200-grain SST, 20 rounds per box. The 200-grain SST is on the lighter, flatter-shooting side of 338 Win Mag hunting weights, and Superformance powder is there to add speed without extra chamber pressure.

Hornady's SST uses a polymer tip to start expansion and an InterLock ring to keep core and jacket together. Superformance is listed 100 to 200 fps faster than a conventional load of the same bullet weight, still inside SAAMI pressure. A 24-inch test barrel shows 3,030 fps and 4,076 ft-lb at the muzzle, 2,830 fps at 100 yards.

This listing is the 338 Win Mag 200-grain SST Superformance box of 20. It is a hunting load for a 338 Winchester Magnum; confirm your rifle is chambered for that cartridge before you buy.
