This is .357 Sig Speer Lawman 125gr. TMJ Clean-Fire Ammo. This ammo is brass cased, boxer primed and 100% non-corrosive. Lawman Clean-Fire is loaded like regular Lawman except for the primer and bullet. The ignition power comes from our patented Clean-Fire primer that contains no lead, barium, or antimony. The lead core is completely and seamlessly encased in jacket material so powder gases can't burn lead off the bullet base. Lawman Clean-Fire leaves the range air and your firearm cleaner. Fired cases don't show the usual soot coating you see in most regular ammunition. Velocities and bullet weights are the same as most Gold Dot products for realistic practice. If you’re looking for high-quality ammunition in traditional reloadable brass, Lawman is your ammunition. This ammo is packed in 50rd. boxes, 1000rds. per case.
