Underwood Ammo 332 XTP 45ACP+P 185gr Jacketed Hollow Point 20 Per Box/10 Case
Underwood Ammo 332 XTP 45ACP+P 185gr jacketed hollow point ammunition pairs Hornady's proven eXtreme Terminal Performance bullets with Underwood's own handload specifications to deliver a round built for reliable expansion and stopping power. If you're running .45 ACP+P in a defensive or duty pistol, this load threads the needle between penetration depth and controlled expansion — the two things that actually matter when you need a round to perform.
The 185-grain XTP projectile is engineered to expand reliably across a range of velocities while maintaining structural integrity, which means you get consistent terminal performance whether you're shooting through barriers, intermediate materials, or soft tissue. Underwood's formulation approach focuses on matching bullet capability with powder charge and primer selection, so the round behaves predictably downrange and in your intended application — whether that's personal defense, competition, or duty use.
You're getting 20 rounds per box with a 10-box case, so this is a serious quantity suitable for range testing, qualification courses, or keeping your carry gun fed with ammunition you trust. The jacketed hollow point design is standard for modern defensive ammunition: it feeds reliably in semiautomatic pistols and resists fouling in the way a quality JHP should.

Frequently Asked Questions
What guns can I shoot this ammo in?
.45 ACP+P ammunition is designed for .45 ACP firearms rated for +P loads. Check your pistol's manual or markings to confirm it's proofed for +P pressure. If your gun is marked only for standard .45 ACP, do not use +P ammunition.
Is this good for self-defense or competition?
This is a jacketed hollow point round engineered for defensive terminal performance, so it's built with personal defense and duty use in mind. Some competition formats may restrict hollow point ammunition — always verify your match rules before showing up with these.
What makes XTP bullets different?
Hornady XTP (eXtreme Terminal Performance) bullets are precision-manufactured to expand reliably while maintaining structural integrity, balancing expansion with penetration depth. They're widely used in defensive ammunition across the industry because that consistency matters when the round counts.
How much ammo am I getting?
This case contains 10 boxes of 20 rounds each, for a total of 200 rounds. It's a standard case quantity suitable for serious shooters who need reliable supply.
