A QUICK "PRIMER" ON 22 TCM AMMO
The 22 TCM, short for Tuason Craig Micromagnum, is a modern cartridge developed through a collaboration between Fred Craig and Rock Island Armory's Martin Tuason. Originally designed to bring rifle-like velocity to the 1911 pistol platform, the .22 TCM round offers a high-performance shooting experience with muzzle velocities exceeding 2,000 fps from handguns and even greater speeds when fired from a 22 TCM rifle.
Standard 22 TCM ammo features a 40-grain jacketed hollow point (JHP) bullet that delivers flat trajectories, rapid expansion, and excellent accuracy. What makes the 22 TCM particularly interesting is its ability to combine the stopping power of high speed with low recoil, giving shooters the feel of a magnum round without the punishing kick. It's especially appealing for those who enjoy dynamic target shooting or want a unique self-defense option.
Compared to traditional handgun calibers like 9mm or .45 ACP, the 22 TCM offers significantly faster velocities and more explosive energy on impact, while still allowing for rapid follow-up shots. Some platforms even allow users to convert between 9mm and 22 TCM by simply swapping barrels and recoil springs, enhancing the round's practicality and value.
In terms of ammunition selection, Armscor remains the go-to manufacturer for factory-loaded 22 TCM ammunition, offering dependable performance in both pistols and carbines. Their 40-grain JHP load is especially popular with target shooters, varmint hunters, and firearms enthusiasts looking to explore something outside the norm.
Whether you're upgrading a 22 TCM rifle, experimenting with a 1911 conversion, or just looking for a flat-shooting alternative to common calibers, the 22 TCM offers a fast, fun, and reliable option with performance that punches well above its size.
TOP CONSIDERATIONS WHEN BUYING 22 TCM AMMO
Buying 22 TCM ammo means understanding the unique strengths of this high-velocity cartridge and ensuring it aligns with your firearm setup and shooting goals. Here's what to keep in mind when selecting the best .22 TCM ammunition for your needs
Purpose: The 22 TCM round shines in both recreational shooting and defensive applications. For plinking or training, standard 40-grain JHP loads offer fast, flat-shooting fun with low recoil and high accuracy. If you're hunting small game or considering personal defense, the cartridge's explosive velocity and rapid expansion make it effective against soft targets, especially at close to moderate ranges.
Availability: As a niche caliber, 22 TCM ammo may not be as commonly stocked as 9mm or .223 Remington. It's wise to purchase in bulk when 22 TCM is for sale, particularly if you shoot frequently or want to ensure a steady supply. Stocking up when in stock helps avoid future gaps in availability.
Firearm Compatibility: Only use 22 TCM ammunition in firearms specifically chambered for it. Many Rock Island Armory pistols and rifles come factory-configured for 22 TCM or offer conversion kits for dual-caliber use (typically 22 TCM and 9mm). Confirm your platform's specs before shooting to ensure both safety and performance.
Choosing a Manufacturer: Armscor is the premier source for 22 TCM ammo, offering factory loads that are both reliable and consistent. As the developer of the cartridge, Armscor's commitment ensures that every .22 TCM round is tested for performance across both handguns and rifles.
Consider Barrel Length: The 22 TCM responds well to longer barrels, especially in rifles like the Rock Island Armory M22 TCM bolt-action. A longer barrel can boost velocity well beyond 2,300 fps, maximizing accuracy and terminal effect. If you're shooting from a pistol, expect slightly lower speeds, but still well above most standard handgun rounds.
