  • 129 Grain SST bullet delivers devastating terminal expansion on impact
  • 2,930 fps muzzle velocity for a flatter trajectory and extended range
  • No increase in felt recoil, muzzle blast, or chamber pressure
  • Minimal temperature sensitivity ensures consistent performance in all conditions
  • Conveniently packaged in 20-round boxes for range or field use

Who This Is For

This load is ideal for deer, elk, and medium-to-large game hunters who rely on the 260 Remington cartridge and demand maximum downrange energy with pinpoint accuracy. It's equally well-suited for precision rifle shooters who want the flattest trajectory available from their 260 Rem without handloading or switching to a wildcat cartridge.

Frequently Asked Questions

What makes Hornady Superformance different from standard 260 Remington ammunition?

Hornady Superformance uses specially formulated progressive propellants that burn more efficiently, squeezing up to 200 fps of additional velocity out of the same cartridge case without generating excess chamber pressure, additional recoil, or increased muzzle blast. This means you get a noticeably flatter trajectory and more downrange energy compared to conventional factory loads, all while keeping your rifle's barrel life and accuracy intact.

What is the SST bullet and how does it perform on game?

The SST (Super Shock Tip) is Hornady's signature polymer-tipped hunting bullet. The tip initiates rapid, controlled expansion on impact even at lower velocities, while the InterLock ring keeps the core and jacket bonded together for deep penetration and high weight retention. On deer-sized game, the 129 gr SST at 260 Remington velocities produces reliable mushrooming and devastating energy transfer, making it a trusted choice for hunters from open plains to dense timber.

Is this ammunition safe to use in standard 260 Remington factory rifles?

Yes. Despite its higher velocity, Hornady Superformance ammunition is loaded to SAAMI-spec pressure limits and is safe to use in any factory-chambered 260 Remington rifle in good condition. The performance gain comes from the advanced propellant formulation, not from over-pressuring the cartridge. Always ensure your firearm is in proper working order and consult your owner's manual if you have questions about ammunition compatibility.
