Hornady Superformance .260 Rem 129gr SST
Hornady Superformance delivers 100-200 fps velocity gains over conventional ammunition without extra recoil or pressure. The 129-grain SST bullet provides flat trajectories and superior energy transfer for hunting and target shooting.
Hornady Superformance .260 Remington Ammunition
Advanced Propellant Technology
Superformance ammunition represents a fundamental shift in how rifle ammunition is engineered. Rather than relying on heavy powder charges and larger cases—which increase recoil and muzzle blast—Hornady uses specialized progressive propellants at normal charge weights. This elegant approach delivers all useable energy directly to the bullet, eliminating the inefficient "rocket nozzle effect" at the muzzle.

Real-World Advantages
Velocity Without Penalty: Superformance ammunition achieves 100-200 fps velocity increases compared to conventional loads—without increases in felt recoil, muzzle blast, or temperature sensitivity. This performance is consistent across all firearms, from semi-automatics to lever-action and pump-action rifles.
Superior Accuracy: The flatter trajectory and reduced wind drift improve accuracy at extended ranges. The SST bullet's design ensures reliable expansion and maximum energy transfer on game.
Consistency and Quality: Each cartridge is loaded to precise specifications with carefully matched primers. Lot-to-lot consistency ensures predictable performance from box to box.
Why Superformance Works
Conventional ammunition design relies on brute force—larger powder charges and bigger cases. Superformance ammunition takes a different approach, using progressive propellants that burn more efficiently. The result is higher velocity with normal pressure levels, delivering better ballistics without the downsides of traditional magnum loads.
Whether you're hunting or shooting at the range, Superformance ammunition gives your .260 Remington the performance edge you need.
Features
- achieves the highest performance of any ammunitinon on the market today with cutting edge technological advancement in ammunition design
- ultra progressive propellants, your favorite sst or gmx bullets achieve levels of performance that are simply unattainable with conventional propellants. in the past, shooters have used a brute force approach of using large charge weights of a slow burning powder in a larger cartridge case which ultimately this leads to more recoil and muzzle blast
