Hornady Superformance 260 Remington ammo delivers measurable velocity gains over standard hunting loads without increasing chamber pressure or felt recoil. This Hornady load uses proprietary propellants to push a 129-grain SST polymer tip bullet to 2930 fps from a 24-inch test barrel — performance typically reserved for handloads or magnum cartridges. The SST bullet features a sharp polymer tip for improved ballistic coefficient (0.485 G1), a one-piece core-and-jacket design with InterLock ring to control expansion, and sectional density of 0.264 for deep penetration on medium game. Brass cases accept Boxer primers and reload reliably. Corrosive-free formulation performs from sub-zero to desert heat.
Built for the Box
The Superformance line bridges the gap between factory hunting ammunition and premium handloads. Standard 260 Remington ammo typically launches 129-grain bullets at 2700-2750 fps; this load adds 180-230 fps without requiring a different action, bolt face, or magazine. Chamber pressure stays within SAAMI specifications — your rifle’s barrel life and brass longevity remain unaffected. The SST bullet’s thin jacket and InterLock ring ensure controlled mushrooming at impact velocities from 1600 fps (effective range on deer-sized game) up to muzzle velocity. Hornady’s polymer tip resists deformation in the magazine and initiates expansion on impact, creating wide wound channels while retaining 70-85% of original bullet weight.

The 260 Remington operates efficiently in short-action rifles — the Superformance load extends effective range on whitetail, mule deer, pronghorn, and similar game by flattening trajectory 1.5-2 inches at 300 yards compared to standard velocity loads.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Always follow the four rules of firearm safety — treat every firearm as loaded, keep muzzle pointed in a safe direction, finger off trigger until ready to fire, be certain of your target and what lies beyond.
- Verify current federal, state, and local ammunition laws before purchasing — some jurisdictions restrict lead-core bullets or magazine capacities.
- This ammunition contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. Store in original packaging away from children.
