Hornady Superformance 80563 is .270 Winchester 140-grain SST, 20 in the box. Superformance powder is Hornady's faster load: they advertise 100–200 fps over a conventional .270 without extra peak pressure. The 24-inch test barrel is 3,090 fps at the muzzle.
Bullet is the InterLock SST. Hornady lists Superformance as safe in semi-autos, levers, and pumps. You get a flatter 140-grain .270 than a standard hunting box, not a reduced-recoil load.
This listing is a 20-round box of 140-grain Superformance SST only.
