Total Copper X-panding (TCX)

Product Overview

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

TCX (Total Copper X-panding) ammunition incorporates a 100% solid copper projectile, with both interior and exterior serrations to ensure maximum expansion. There is no bi-metalic bonding to separate or otherwise fail, as can occur with JHP (Jacketed Hollow Point) projectiles.

The result is consistent penetration that meets or exceeds FBI standards, and expansion that reliably outperforms typical JHP (Jacketed Hollow Point) projectiles.


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.
