FMJ-FN bullets are engineered for non-expanding, deep penetration, making them ideal for woods defense. Whether you're facing wild hogs, black bears or other dangerous game, these bullets offer reliable stopping power. The flat nose (FN) design allows for superior penetration through dense mass, maintaining a nose-forward position that maximizes impact. Unlike round nose alternatives, the flat nose optimizes penetration efficiency. Featuring nickel-plated brass casings, these rounds offer improved feeding in all firearm actions, enhanced corrosion resistance, better aesthetics and easier cleanup during reloading. Nickel plating prevents tarnishing, even during extended storage or exposure to moisture, leather and other materials. Like all Underwood Ammo products, these rounds use flash-suppressed powder to preserve your vision in low-light conditions. Field-tested with popular firearms, this high-performance ammunition ensures reliability in real-world environments. These new production, non-corrosive rounds come in boxer-primed, reloadable brass cases for added convenience.
