Speer TMJ 380ACP 95gr Total Metal Jacket 100 Per Box components offer a cleaner, more precise shooting experience. Using Uni-Cor technology, Speer electrochemically bonds a copper jacket over the entire lead core. This eliminates the exposed lead base found on standard FMJ bullets, preventing lead vaporization from propellant heat. It is an ideal choice for indoor ranges and ported barrels. Double-swaged for diameter consistency, these bullets provide match-grade accuracy and reliable cycling in semi-auto pistols. Designed for high-volume training, they deliver the quality needed for consistent performance and improved air quality at the firing line. Defensive Application Non-expanding TMJ bullets are designed for target practice. They carry a high over-penetration risk and do not create large wound channels, making them unsuitable for personal defense.
