Federal Syntech Range Pistol Ammo 40 S&W 165 gr. TSJ 50 rd.

Like all Syntech loads, they feature the exclusive Total Synthetic Jacket (TSJ), which prevents metal-on-metal contact between the bullet and barrel, eliminating copper and lead fouling as well as reducing damaging heat and friction. Combined with clean-burning powders and the Catalyst lead-free primer, Syntech Action Pistol provides the softest-shooting and most reliable performance possible for high-volume competitive shooters.
