Experience superior performance in the field with Hornady Superformance .270 130gr SST ammunition. Engineered for hunters seeking increased velocity and uncompromising accuracy, this ammunition delivers 100 to 200 fps faster speeds than conventional loads, without an increase in felt recoil or muzzle blast. The SST (Super Shock Tip) bullet ensures reliable expansion and energy transfer, making it ideal for hunting medium to large game, including deer.

Key Features:

• Superformance Technology: Delivers 100 to 200 fps faster velocity compared to conventional ammunition, without increased felt recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy. This consistent performance is achieved across all calibres, bullet weights, and types, exceeding SAAMI standards.
• SST (Super Shock Tip) Bullet Design: Features a polymer tip for an increased ballistic coefficient, a secant ogive for flat trajectories, and a boattail profile for enhanced speed and energy retention. The Interlock Ring ensures reliable expansion and excellent core-jacket retention upon impact.
• Specialised Propellants: Utilises ultra-progressive powders optimised for SST or GMX bullets, delivering performance levels unattainable with conventional propellants.
• Versatile Application: Safe for use in all firearms, including semi-autos, lever guns, and pump actions.
• Gas-Operated Firearm Compatible: Engineered to operate safely within SAAMI pressure guidelines for gas-operated firearms, though performance may vary slightly between different gas systems.

Hornady Superformance ammunition employs an elegant approach to velocity enhancement. Instead of a brute-force method with large charge weights, it uses specialised powders at normal charge weights, imparting all usable energy to the bullet. This significantly increases velocity while reducing the "Rocket Nozzle Effect" at the muzzle.

Hunters will appreciate the increased rifle performance, absence of increased barrel wear, and superior temperature stability realised with Superformance ammunition. While perfectly safe for gas-operated firearms, Hornady's testing indicates that some gas systems may perform better than others with this ammunition.
