Description With its increased speed, Superformance produces flatter trajectories and less wind drift for improved accuracy as well as better energy transfer for maximum terminal performance. Highly efficient propellants accelerate the bullet longer, resulting in up to 200 fps increase in muzzle velocity, without additional peak pressure, boosting velocity without extra recoil. The ultimate all-around performer, Superformance is safe in all types of firearms including semi-autos, lever guns, and pump actions.Caliber: 7mm Rem MagRounds Per Box: 20Casing Material: BrassMuzzle Energy: 3302 ft lbsMuzzle Velocity: 3030 fpsGame Type: MediumApplication: HuntingBoxes Per Case: 10Bullet Type: Super Shock TipBullet Weight: 162 gr
