Speer - Total Metal Jacket - 125 Grain 357 Sig Ammo - 1000 Rounds

The science is settled — breathing in vaporized lead is not good for your health. For a shooter, that’s a problem, because hot propellant gasses will evaporate the lead in a conventional bullet’s core during ignition. Speer solves that problem with this 357 SIG cartridge, which features a 125 grain total metal jacket projectile.

A TMJ provides all the benefits of a full metal jacket, including the prevention of rapid bore fouling. It furthermore encapsulates the bullet’s base, shielding the core’s lead from the heat that would have otherwise aerosolized it. This round’s bullet also has a flat meplat, suiting it perfectly for training with paper targets.

Speer’s new production brass shell casing is expertly tapered, so it will fit perfectly in any 357 SIG pistol’s chamber. It’s also reloadable, a boon for any handloader. This round’s primer and propellant also burn clean, making it as good for your handgun as it is for you!
