Federal’s HST ammunition was designed for use by law enforcement professionals, and indeed was available exclusively to them for some time. If you value a personal defense load that can tackle barriers and neutralize a threat quickly, and which performs admirably on the FBI’s test protocol, then this 10mm cartridge is for you.

This round’s 200 grain projectile wears a cannelure that tightly binds its core and jacket together. It is able to hold on to a fantastic percentage of its weight because of it, even if it has to pierce denim, sheetrock, or one of a variety of other barriers. The bullet still reliably expands to the shape of a six-pointed star after having passed through a barrier thanks to its specially engineered nose cavity and the skives in its jacket.

The HST bullet’s nose profile promotes smooth feeding in a semi-automatic, as does its glossy nickel plated brass casing. That kind of dependability is indispensable in a self-defense load, so with these rounds in your magazine you can go about your business with confidence.
