One of the great things about this ammunition are high quality features that make this ammunition perfect choice for self-defense ammunition. Each round of ammunition is loaded into a Federal Premium nickel plated brass case with waterproofing on the case mouth and primer. Every load has a consistent powder charge and reliable primer for consistent ignition. Every HST bullet features a tapered jacket profile for reliable feeding, a cannelure that locks the copper jacket to the lead core, patented co-aligned internal and external skiving and a deep tapered hollow point that will not clog.
