Product Overview
The Hornady Superformance .260 Remington delivers a 129-grain SST bullet at 2930 feet per second, generating 2459 foot-pounds of muzzle energy. This velocity puts it ahead of standard .260 Remington loads by a significant margin thanks to Hornady's proprietary Superformance propellants. The combination of speed and the SST's streamlined profile with a 0.485 ballistic coefficient means this round maintains energy effectively at extended distances where other loads begin to fall short.
What sets this load apart is the SST bullet's construction. The polymer tip initiates expansion reliably across a wide velocity window, while the InterLock ring keeps the core and jacket together during penetration. This design creates consistent wound channels whether you connect at 100 yards or push out past 400. The secant ogive profile reduces drag, helping the bullet buck wind better than traditional soft points in the same weight class.
Hunters pursuing whitetail, mule deer, and antelope will find this ammunition well-suited for their needs. The flat trajectory makes holdover estimation simpler at unknown distances common in western hunting. For eastern hunters in mixed terrain, the combination of moderate recoil and decisive terminal performance makes it effective from tree stands to food plot edges. This load also handles feral hogs well, with enough energy and expansion to anchor them quickly.
- Superformance propellants achieve 2930 fps—roughly 100-150 fps faster than competing .260 Remington loads with similar bullet weights
- The SST's InterLock ring provides reliable weight retention during expansion, reducing the chance of bullet fragmentation on heavy bone
- Higher velocity extends the effective hunting range by maintaining energy above 1500 ft-lbs past 400 yards
- Polymer tip ensures consistent expansion initiation even at lower impact velocities encountered at extended range
- The 0.485 BC falls behind premium match bullets like the ELD Match (0.554) and RDF (0.615), resulting in more wind drift at extreme range
- SST bullets may expand aggressively on lighter-bodied animals at close range, potentially causing excessive meat damage
- Superformance loads tend to command a price premium over standard hunting ammunition
- Not optimized for precision target work—designed primarily as a hunting projectile
