    Product Description

    357 Magnum Total Copper X-panding (TCX)

    Developed as a Defiant Munitions Skunkworks project, our .357Magnum Total Copper X-panding load features our monolithic 100% copper hollow-point, with a muzzle velocity of 1,325 feet per second and 487 foot pounds of energy, as tested in a Smith & Wesson model 686 with a 4.125in barrel, providing 16in of penetration through denim and ballistics gelatin during testing conducted to FBI specifications.

    It provided 1,150fps and 13.25in of penetration from a Smith & Wesson model 340PD with a 1.875in barrel during testing conducted to FBI specifications.

    Packaged 20 rounds per Box, we build these to our exacting standards to ensure you have only the most consistent and reliable ammo available.

    DEFIANT MUNITIONS uses only the highest quality primers, powder, brass casings and projectiles in all of our Premium Defensive ammunition.

    At DEFIANT MUNITIONS, we don’t simply test each new product upon release. We test every lot of ammunition for muzzle velocity, muzzle energy, penetration depth, expansion rate and weight retention to the highest standards. We go the extra mile to ensure maximum performance and consistency. Additionally, every round is inspected and chamber checked by hand before packaging.
