Hornady Superformance 300 Winchester Magnum 180 Grain SST Rifle Ammunition

Hornady Superformance 300 Winchester Magnum ammunition delivers up to 200 fps velocity gains without increasing chamber pressure, recoil, muzzle blast, temperature sensitivity, fouling, or accuracy loss. The Superformance(R) line uses progressive propellants that elevate V-MAX,(R) NTX,(R) SST,(R) GMX,(R) InterLock,(R), and InterBond(R) bullets to performance levels beyond what conventional ammunition can achieve. This 180 grain SST load represents the technology’s application to magnum rifle shooting.
