The optimized fluted nose design transfers energy through fluid displacement to create an exceptionally large permanent wound cavity while maintaining dependable penetration (up to 18 inches within FBI guidelines). This non-expanding, lead-free bullet design helps reduce concerns associated with hollow point expansion failures through common barriers such as wallboard, sheet metal, and automotive glass. Nickel-plated brass cases are used to enhance feeding, improve corrosion resistance, and keep ammunition looking cleaner in storage, making this a strong choice for both personal protection and hunting applications.\u003c\/p\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid monolithic copper, fluted Xtreme Defender projectile for barrier-blind defensive performance\u003c\/li\u003e\n  \u003cli\u003eLead-free design with optimized flute geometry to create a large permanent wound cavity\u003c\/li\u003e\n  \u003cli\u003eHigh-velocity .380 ACP loading (listed 1300 fps) delivering strong energy in a lightweight projectile\u003c\/li\u003e\n  \u003cli\u003eNickel-plated brass cases for improved feeding, enhanced corrosion resistance, and easier cleanup for reloaders\u003c\/li\u003e\n  \u003cli\u003eNew production, non-corrosive, boxer-primed, reloadable brass-case ammunition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Underwood Ammo\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 678\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 816874023683\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCartridge:\u003c\/strong\u003e .380 ACP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBullet Weight:\u003c\/strong\u003e 68 gr\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBullet Type:\u003c\/strong\u003e Xtreme Defender (fluted), solid monolithic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBullet Material:\u003c\/strong\u003e Copper (lead-free)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e Nickel-plated brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRounds Per Box:\u003c\/strong\u003e 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Velocity (listed):\u003c\/strong\u003e 1300 fps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Energy (listed):\u003c\/strong\u003e 255 ft-lbs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimer:\u003c\/strong\u003e Boxer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosive:\u003c\/strong\u003e No (non-corrosive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReloadable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePenetration Performance (stated):\u003c\/strong\u003e Up to 18 inches (within FBI guidelines)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBallistic Coefficient (G1, stated):\u003c\/strong\u003e 0.087\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSectional Density (stated):\u003c\/strong\u003e 0.0770822116\u003c\/li\u003e\n\u003c\/ul\u003e\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.
