Hornady Ammunition 175 Grain Jacketed Hollow-Point (JHP) Ammo Details

For those who carry a firearm chambered in the mighty 10mm Auto, it's hard to beat Hornady Critical Duty as a carry load. This ammunition fires a 175 grain Flexlock hollow point bullet that can negate an attacker's use of various forms of cover including plywood, sheet metal, and auto glass. The Flexlock bullet is designed to punch through these barriers; its soft polymer tip keeps debris clear of the expansion cavity and delivers more reliable terminal performance upon contact with the target.

Firing 5 rounds through a 4-layer barrier and into synthetic gelatin, you can see this Hornady penetrated about 23.5" and provided an expanded bullet diameter of about half-an-inch.
