.223 55gr Solid Copper Defensive Ammunition

Built with Lapua brass casings, the TCX223 is a 55 grain, .223 Solid Copper Defensive round, with a muzzle velocity of 3,100 feet per second and 1,174 ft/lbs of muzzle energy, as tested in a 18.0 inch 1/8 twist barrel.

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


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-metallic bonding to separate or otherwise fail, as can occur with JHP (Jacketed HollowPoint) projectiles. The result is consistent penetration that meets or exceeds FBI standards, and expansion that reliably outperforms typical JHP (Jacketed HollowPoint) 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.
