Hornady

Hornady .338 Ruger Compact Magnum 225 Grain SST SPF rounds increase your rifle's performance up to 200 fps without extra chamber pressure, recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy. Superformance uses progressive propellants that take your favorite V-MAX, NTX, SST, GMX, Interlock, and InterBond bullets to levels of performance that are simply unattainable with conventional ammunition.
