The .22 GT cartridge is derived from the 6mm GT case, modified to accommodate a .22 Cal projectile. It provides similar advantages to the 6 GT, including higher velocities and flatter trajectories, while offering reduced recoil due to the smaller caliber. Each .22 GT case manufactured by Alpha Munitions features the company's Optimized Case Design (OCD) with advanced case head technology. This innovation is intended to extend the lifespan of the primer pocket and the case itself, even under elevated pressures and velocities. The .22 GT brass is designed for use with small rifle primers.

• Primer pockets precisely engineered to accommodate small rifle primers
• Advanced enclosure architecture featuring enhanced case head technology for superior performance and efficiency
