- The .22 TCM (Tuason, Craig, Micromagnum) is a proprietary bottlenecked rimless cartridge derived from a 5.56×45mm NATO (.223 Remington) parent case. It was developed by custom gunsmith Fred Craig in collaboration with Martin Tuason, the President of Rock Island Armory (RIA) and Armscor. The cartridge is primarily used in Rock Island Armory M1911 pistols and the M22 TCM bolt-action rifle. Initially known as the .22 Micro-Mag, the .22 TCM is conceptually similar to other bottlenecked pistol cartridges, such as the 7.62×25mm Tokarev and the FN 5.7×28mm. The design prioritizes high velocity and reduced recoil by trading bullet mass for speed, making it suitable for various applications.
