Speer TMJ Component Bullets Copper .40 / 10mm 180 Grain 400-Count

Overview

Speer TMJ Reloading Bullets Features The Speer TMJ bullet features a total metal jacket construction that fully encases the lead core eliminating exposed lead at the base and significantly reducing airborne lead particles during shooting for a cleaner range experience. A ballistic coefficient of .143 and sectional density of .161 reflect the efficient and well-proportioned design of this 180-grain projectile optimized for the velocities typically achieved in .400-inch diameter target loads. The total metal jacket construction also reduces barrel fouling compared to traditional lead or partial jacket projectiles keeping the bore cleaner through extended high-volume shooting sessions. The total metal jacket provides a uniform and consistent bearing surface that promotes accurate and repeatable performance through the barrel while protecting the lead core during loading and feeding. At .400 inches in diameter and .600 inches in overall length these projectiles are dimensionally consistent and ready to load straight from the box without the need for additional sizing or prep work. The 180-grain weight is one of the most popular and widely used .400-inch diameter projectile weights offering an outstanding balance of velocity accuracy and recoil management for target shooting applications. Packaged in bulk boxes of 400 the Speer TMJ delivers exceptional value for high-volume handloaders who load in quantity for target shooting applications. Speer s reputation for manufacturing consistency ensures that each projectile meets the same exacting dimensional and weight standards delivering the load-to-load uniformity that accurate handloading demands. For .400-inch diameter handloaders seeking a clean-shooting reliable and proven total metal jacket bullet at a competitive price the Speer TMJ is the definitive choice.
