Hornady SuperFormance 300 Win Mag 180gr SST – 20 Rounds

Hornady's SuperFormance 300 Winchester Magnum loads push a 180-grain SST (Super Shock Tip) bullet to magnum velocities without the pressure spike or excessive muzzle blast typical of hot handloads. The polymer-tipped SST is engineered for rapid, controlled expansion on medium to large game — the secant ogive profile and boattail base deliver flat trajectories and high ballistic coefficients, while the InterLock ring mechanically bonds the core and jacket to retain weight through bone and tissue. SuperFormance propellants maximize velocity in standard SAAMI-spec chambers, giving you 100–200 fps more than conventional loads without shortening barrel life or increasing felt recoil.

Chambered in any 300 Winchester Magnum rifle — bolt-action hunting rifles, precision gas guns, and long-range platforms. Hornady uses premium brass cases and carefully matched primers for lot-to-lot consistency. Sold in 20-round boxes; 200 rounds per case.
