This cartridge pairs Hornady eXtreme Terminal Performance (XTP) Jacketed Hollow Point bullets with Underwood’s carefully formulated load design to deliver controlled expansion and deep penetration. Nickel-plated brass cases help promote smoother feeding and enhanced corrosion resistance while staying cleaner in storage and during reloading. Like other Underwood loads, it uses flash-suppressed powder to help preserve vision in low-light defensive situations. These rounds are new production, non-corrosive, boxer primed, and reloadable.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e10mm Auto 180 grain Hornady eXtreme Terminal Performance (XTP) Jacketed Hollow Point for controlled expansion and penetration\u003c\/li\u003e\n  \u003cli\u003eNickel-plated brass cases for improved feeding, corrosion resistance, and easier cleanup\u003c\/li\u003e\n  \u003cli\u003eFlash-suppressed powder helps reduce muzzle flash in low-light conditions\u003c\/li\u003e\n  \u003cli\u003eNew production, non-corrosive, boxer-primed, reloadable cases\u003c\/li\u003e\n  \u003cli\u003eHigh-energy performance suited for hunting and personal defense applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand Name: UNDERWOOD AMMO\u003c\/li\u003e\n  \u003cli\u003eManufacturer Part Number: 243\u003c\/li\u003e\n  \u003cli\u003eUPC: 816874020859\u003c\/li\u003e\n  \u003cli\u003eCartridge: 10mm Auto\u003c\/li\u003e\n  \u003cli\u003eBullet Type: Jacketed Hollow Point (Hornady XTP)\u003c\/li\u003e\n  \u003cli\u003eBullet Weight: 180 grain\u003c\/li\u003e\n  \u003cli\u003eBullet Diameter: 0.400 in\u003c\/li\u003e\n  \u003cli\u003eMuzzle Velocity: 1300 fps\u003c\/li\u003e\n  \u003cli\u003eMuzzle Energy: 676 ft-lbs\u003c\/li\u003e\n  \u003cli\u003eCase Material: Nickel-plated brass\u003c\/li\u003e\n  \u003cli\u003ePrimer: Boxer\u003c\/li\u003e\n  \u003cli\u003eCorrosive: No (non-corrosive)\u003c\/li\u003e\n  \u003cli\u003eReloadable: Yes\u003c\/li\u003e\n  \u003cli\u003eRounds per Box: 20\u003c\/li\u003e\n  \u003cli\u003eBoxes per Case: 10\u003c\/li\u003e\n  \u003cli\u003eCountry of Manufacture: United States of America\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
