Underwood Ammo 246 Xtp 10Mm 200Gr Jacketed Hollow Point 20 Per Box/10 Case

Underwood Ammo 246 XTP 10mm jacketed hollow point ammunition delivers serious stopping power for defensive carry and hunting applications. Built on nickel-plated brass cases and loaded with 200-grain XTP bullets, these rounds are engineered to expand reliably on impact while maintaining structural integrity. New production, boxer-primed, and reloadable, this is ammunition built to perform when it matters most.

Each round leaves the barrel at 1250 feet per second, generating 694 foot-pounds of muzzle energy—sufficient velocity to ensure the hollow point does its job. The projectiles are supersonic, meaning they break the sound barrier and deliver that proven energy downrange. At 0.4 caliber with a sectional density of 0.179, the 200-grain XTP is engineered for deep, consistent penetration and expansion in soft tissue, making it a legitimate choice for both personal defense and hunting medium-sized game where reliability matters.

Non-corrosive and suppressor-safe, Underwood 10mm XTP rounds work in modern suppressors without complications. The brass cases are reloadable, so serious shooters can recycle brass for handloads and reduce long-term ammunition costs. Each box contains 20 rounds; cases are sold in 10-box increments, so you're ordering a full case of 200 rounds.

If you carry a 10mm, hunt with one, or run it at the range, Underwood's XTP load is a no-compromise option that respects both the capability of the cartridge and the responsibility that comes with it.
