About .22 TCM Ammunition

The .22 TCM (Tuason Craig Micromagnum) is a high-velocity bottlenecked cartridge designed to deliver rifle-like performance from handgun platforms. Developed by Fred Craig and Rock Island Armory in 2011, the .22 TCM was created by necking down a .223 Remington case to accept .224-inch diameter bullets, achieving impressive velocities exceeding 2,000 fps from pistol barrels. The .22 TCM is highly regarded for its flat trajectory and minimal recoil due to its exceptional velocity, negligible drop at typical handgun ranges, and effective performance on small game and varmints with specialized firearms designed for this unique cartridge.

Types of .22 TCM Loadings

• Jacketed Hollow Point (JHP):JHP loadings feature hollow point projectiles which are adorned with a full metal jacket. These loadings are generally found in the form of defensive ammo offerings and are designed to facilitate reliable expansion upon impact. Additionally, these types of loadings are designed to achieve adequate levels of penetration for defensive purposes while not overpenetrating the target and risking collateral damage. A good hollow point loading is one that achieves an appropriate level of penetration while expanding reliably upon impact within the target.

Firearms that Use .22 TCM Ammo

Prospective firearm purchasers will find that .22 TCM is mainly supported by handgun offerings from Rock Island Armory/Armscor. In short, one will have to stick to the pistols offered by Rock Island if they want to make use of .22 TCM ammo.
