The Hornady Superformance .223 Remington 53 Grain Varmint Centerfire Rifle Ammo combines powders to specific cartridges and bullet-types for increased velocitoesby as much as 200 fpswithout increasing pressure or recoil. The added velocity flattens trajectory and increases foot pounds of energy, which in turn increase your odds of clean kills at extended ranges. Superformance Varmint ammunition is loaded with either lead-core V-MAX or lead-free NTX bullets. Both bullet types feature polymer tips and streamline profiles with high ballistic coefficients that flatten trajectory and reduce wind drift, making them highly effective for long-range shooting. Upon impact, the polymer tip pushes back into the core to deliver dramatic expansion on light-skinned varmints and predators, over a wide range of distances and velocities. Concentric, AMP bullet jackets produce match-grade accuracy. Hornady Superformance Varmint Centerfire Rifle Ammo develops pressures safely within SAAMI guidelines, and is compatible with gas operated, semi-auto firearms with 20″ barrels or longer, or with shorter-barreled semi-autos using adjustable gas systems. Reloadable brass cases. Made in USA. Up to 200 fps faster than standard ammo Lead-core V-MAX or lead-free NTX bullets No increase in pressure or recoil High ballistic coefficients Flat trajectory Minimal wind drift Excellent accuracy Explosive expansion Reloadable brass cases
