Underwood Ammo XTP rounds stand out for their formidable power and pinpoint accuracy. We use Hornady's eXtreme Terminal Performance (XTP) bullets, engineered for deep penetration, exceptional accuracy and controlled expansion. By pairing these advanced XTP bullets with our proprietary design, we deliver a round that is both highly effective and reliable. Our nickel-plated brass casings offer several benefits: they ensure smoother feeding in all firearm actions, provide superior corrosion resistance compared to traditional brass and enhance both appearance and ease of reloading. Unlike brass, nickel-plated casings resist tarnishing from exposure to leather, moisture and other materials. As with all Underwood Ammo products, our XTP rounds feature flash-suppressed powder to protect your vision in low-light conditions. This high-performance ammunition is rigorously field-tested with popular real-world firearms to ensure reliability under all conditions. It is newly produced, non-corrosive and comes in boxer-primed, reloadable brass cases.
