Federal Syntech Range 10mm Auto Ammo 205 Grain Federal TSJ Total Synthetic Jacket (TSJ) Case of 500 (10 Boxes of 50)

The polymer coating on the American Eagle Syntech ammunition prevents harsh metal-on-metal contact between the bullet and bore, eliminating copper and lead fouling. In internal testing against conventional FMJ ammunition, Syntech produced an average of 12 percent less barrel friction and 14 percent less heat. It also eliminates lead and copper fouling. Combined with clean-burning powders and the Catalyst lead-free primer, Syntech loads keep your gun cleaner, longer, so you can shoot more-and shoot better.
