CCI Ammunition markets the Speer Lawman Clean-Fire line in .357 Sig (brand part no. 54232) with a 125-grain total metal jacket bullet built specifically for indoor range shooting. Clean-Fire ammunition uses a primer formulated without lead, barium, or antimony, cutting down on the airborne particulate that concerns indoor range operators and frequent shooters alike. The TMJ bullet takes that a step further by fully encasing the lead core in copper, including the base, so propellant gases can’t burn lead off the bullet the way they can with a standard FMJ. For .357 Sig shooters who train indoors on a regular basis, this handgun ammunition is built with that environment in mind.
