Speer Ammo 4399 TMJ .40 Cal 155gr Total Metal Jacket Reloading Bullets - 100/Box

The Speer 4399 TMJ is a .40 Caliber handgun reloading bullet built for clean, accurate target shooting. Speer uses its proprietary Uni-Cor process to completely encase the 155 grain lead core in a seamless copper jacket, eliminating the exposed lead base found on conventional FMJ designs. The result is reduced fouling, smoother feeding, and more consistent performance downrange compared to standard full metal jacket projectiles.

Measuring .400" in diameter with an overall length of .538", this Total Metal Jacket bullet is intended for handloaders building .40 S&W, 10mm Auto, and other .400" diameter handgun cartridges. It carries a ballistic coefficient of .125 and a sectional density of .138, making it well suited to range, training, and general-purpose practice ammunition where accuracy, cleanliness, and economy matter. Each box contains 100 bullets.

These are reloading projectiles only and do not include brass, primers, or powder. Reloaders will appreciate the consistency Speer puts into every TMJ bullet, whether producing range rounds, training ammunition, or general-purpose practice loads for .40 caliber and 10mm platforms.
