Federal Syntech 40 S&W 165 Grain ammunition delivers the clean-shooting benefits of synthetic jacket technology in a full-power load built for serious practice and duty use. Each round pairs a 165-grain Total Synthetic Jacket (TSJ) bullet with Federal's proven reloadable brass casing, giving you range-proven reliability at a practical price point. Whether you're working through drills at the indoor range, zeroing a carry gun, or running competition stages, Syntech rounds let you train with the exact load you'll trust when it counts.
The standout feature here is the TSJ bullet's polymer coating, which eliminates direct metal-on-metal contact between the bullet and barrel. That means significantly less copper and lead fouling buildup during extended shooting sessions—your bore stays cleaner, accuracy doesn't fade from carbon ring creep, and you spend more time actually practicing instead of scrubbing the gun. The lead core and copper jacket deliver consistent ballistics, while the Syntech polymer reduces splashing and fouling that plagues conventional jacketed rounds, especially important in indoor ranges where lead concerns matter.
Federal packages these in convenient 50-round boxes (or bulk 500-round cases if you're running volume), and the reloadable brass means you can handload fresh rounds once fired. The 165-grain TSJ is a full-power .40 S&W load, so you're training with the same velocity and handling characteristics as your duty or defensive ammo—not underpowered practice loads that don't cycle the gun the same way.
| Cartridge | .40 S&W |
| Bullet Weight | 165 grains |
| Bullet Type | Total Synthetic Jacket (TSJ), round-nose |
| Case Type | Reloadable brass |
| Package | 50 rounds per box; 500 rounds per case (10 boxes) |
Syntech ammunition is designed to feed reliably in modern .40 S&W pistols. If your gun cycles standard .40 S&W factory ammo, Syntech should feed without issue. Always verify your gun's compatibility and test thoroughly with any new ammunition before relying on it for carry.
Federal Syntech rounds use a unique polymer coating on the bullet that prevents direct metal-on-metal contact with the barrel. This dramatically reduces copper and lead fouling, keeping your bore cleaner during long shooting sessions and preventing the accuracy fade that can come from heavy carbon buildup, especially on indoor range days.
Yes—Federal packages Syntech in reloadable brass cases, making it an economical choice for handloaders. Once fired, you can process, reload, and resize the brass using standard .40 S&W reloading tools and dies.
Yes. The 165-grain Syntech load is a full-power .40 S&W round, so you're training with the same velocity and dynamics as your duty or defensive ammunition—not underpowered practice loads that cycle differently.
