Hornady 7mm SST BulletsShort 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 SST creates a devastatingly large wound channel. Box of 100. . 284" dia
