HORNADY 270 WIN - 140 GR - SST - 20 RDS/BOX
The Hornady Superformance 270 Winchester 140 Grain SST delivers a revolutionary leap in rifle ammunition performance, pushing velocities up to 200 fps faster than conventional loads — without added pressure, recoil, or fouling.
- Superformance propellant technology achieves 3,090 fps muzzle velocity in 270 Win
- 140-grain SST bullet offers devastating terminal expansion and deep penetration
- Polymer tip initiates reliable expansion at both close and extended ranges
- No increase in chamber pressure, muzzle blast, or felt recoil over standard loads
- Low temperature sensitivity ensures consistent performance in all hunting conditions
- Conveniently packaged in 20-round boxes for range and field use
Who This Is For
This ammunition is ideal for deer, elk, and big-game hunters who demand maximum downrange energy and flat trajectories from their 270 Winchester rifles. Whether you're shooting across open plains or through timber at moderate ranges, the Hornady Superformance SST gives you the confidence of faster, more explosive terminal performance without having to handload or sacrifice consistency.

Frequently Asked Questions
What makes the SST bullet different from standard soft-point hunting bullets?
The SST (Super Shock Tip) features a precision polymer tip that initiates rapid, controlled expansion on impact across a wide range of velocities. Unlike traditional soft-point bullets, the polymer tip resists deformation in the magazine, produces a higher ballistic coefficient for a flatter trajectory, and delivers consistent mushrooming even at longer ranges where velocity has dropped. The result is devastating energy transfer and reliable terminal performance on medium to large game.
Is this ammunition compatible with all standard 270 Winchester rifles?
Yes. Hornady Superformance 270 Win 140 Grain SST is loaded to SAAMI-spec pressure levels and is compatible with any standard 270 Winchester chamber. Despite the increased velocity, chamber pressure remains within safe limits, making it suitable for bolt-action hunting rifles from all major manufacturers including Remington, Ruger, Winchester, Savage, and Tikka.
How does the 140-grain SST perform on deer and elk at longer ranges?
The 140-grain SST is an excellent all-around big-game projectile for 270 Win. Its high ballistic coefficient (G1: 0.520) and 3,090 fps muzzle velocity combine to retain significant energy at extended distances — approximately 1,900+ ft-lbs at 400 yards — making it effective for ethical kills on whitetail deer, mule deer, and even elk at moderate to long hunting ranges. The polymer tip ensures reliable expansion even when velocity has decreased at distance.
