Short for "super shock tip," the hornady sst is designed to deliver tremendous shock on impact while expanding quickly and reliably, particularly at higher velocities.Flat shooting and deadly accurate, it's an ideal bullet for whitetails, as well as most north american game animals from antelope to moose and similar-sized african plains game.The sleek polymer tip increases the ballistic coefficient, while the secant ogive boat-tail profile gives hunters the speed, ballistic efficiency and downrange energy they're looking for.It utilizes an interlock ring which ensures the core and jacket remain locked solid during expansion.Coefficient: .510Bullet Type: Super Shock TipBullet Diameter: .264Weight: 123 grBullet Caliber: 6.5mmJacket Material: CopperBullet Tip Material: PolymerCore Material: LeadCannelure: YesSectional Density: .252Quantity: 100 Per Box
