.270 Winchester 140 gr SST Superformance Ammunition

Description

Hornady Superformance .270 Winchester ammunition uses proprietary propellants engineered to push your rifle harder while keeping pressure, recoil, and muzzle blast in check. The 140-grain Super Shock Tip bullet gives you a flatter trajectory and more downrange energy than conventional loads, making it a solid choice for hunting situations where every yard counts.

What Makes Superformance Technology Work

The secret is the progressive propellant blend. Instead of cramming in more powder the old-fashioned way, Hornady's custom powder burns smarter to achieve velocities up to 200 feet per second faster than standard factory loads. You get that speed boost at 3090 fps without the punishing recoil that comes with traditional magnum approaches. Temperature stability is excellent too, so this ammo performs consistently whether you're hunting in cold morning conditions or hot afternoons. Everything uses quality brass cases and primers for reliable feeding and firing across different rifle actions.

The SST Bullet Design and Terminal Performance

The 140-grain InterLock SST bullet combines a polymer tip with Hornady's proven InterLock ring system. That ring mechanically locks the jacket and core together, which means the bullet retains weight during expansion and penetrates deep into vital organs. The HeatShield polymer tip won't warp at long range like older designs, keeping ballistics consistent. When it hits, the tip acts as a wedge to initiate controlled expansion while the reinforced jacket stays intact. The result is a bullet that expands reliably across a wide range of impact velocities, from close-range hunting scenarios to longer shots where velocity has dropped.

Application and Performance Profile

With a ballistic coefficient of 0.495 and that flatter trajectory, this load works well for medium to large game hunting. Muzzle energy sits at 2968 foot-pounds. The 140-grain weight splits the difference between lighter, faster options and heavier, harder-hitting rounds, making it versatile across different .270 Winchester rifles. These rounds come packaged 20 to a box, giving you a standard hunting load setup.
