    Product Description

    300 BLACKOUT 200 gr TCX-Subsonic

    Built with all new components, the 300 BLACKOUT 200 gr TCX-Subsonic is a 200 grain, 300 BLACKOUT caliber Solid Copper, Subsonic Defensive round, with a muzzle velocity of 1,000 feet per second and 444 ft/lbs of muzzle energy, as tested in a standard 12 inch, 1 in 8 twist barrel.

    Upon testing with ballistic gelatin to FBI specifications, the 200gr TCX-Subsonic expands to .830 inches, with 100% bullet weight retention, and 14 inches of penetration.

    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% monolithic, 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.

    The brass for this ammunition receives a proprietary, TPD plating giving 5X the lubricity compared to non-plated brass. This corrosion resistant plating won't crack or flake, like nickle plating can, and improves extraction and ejection of spent brass.

    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.

      Great hunting round. I used this to shoot hogs in TX and was very impressed with the terminal performance of the round. Even on a poorly placed shot, the pig didn't make it more than 50 yards after being hit. I've already stocked up for the next hunt.

      Since this is defensive ammo for my home defense MCX, I have only shot about half of what I purchased. These rounds are the highest of quality and super quiet when shooting suppressed through my SiCo Omega. Beyond impressed and I can’t wait for them to be back in stock so I can buy more.

      Flawless performance and amazing accuracy in my Sig Rattler Canebrake. I have a new favorite manufacturer for 300 BLK ammo. It is well worth the price.
