What is the 22 GT: 

22 GT (as the name suggests) is a .22 caliber version of the 6mm GT which was birthed from a collaboration between George Gardner (owner GA Precision) and Tom Jacobs (owner Vapor Trail Bullets).

The intention of the 22 GT is to offer the same benefits of the 6mm GT (feeding (unmodified AICS magazines/standard short action receivers), properly headstamped brass and appropriate case volume for lower SD velocities); and provide higher speeds, flatter trajectories for wider point blank kill ranges, potential for lower recoil impluse and less damage to capes for fur hunters. 


  • Brass: Alpha Munitions, available through GA Precision
  • Powder: Hodgdon Varget, Reloader16, Winchester 6.5 Staball are some starting recommendations. 
  • Dies: We recommend using a 6mm GT Bushing style die (GAP carries RCBS Matchmasters and Redding Competition bushing dies) and swapping the for apporpriate bushing to your neck tension preference.
