The 6MM GT (GAP T1100) is a relatively new rifle cartridge developed through a collaboration between George Gardner of GA Precision and Tom Jacobs of Vapor Trail Bullets. It was designed to offer superior performance for precision rifle competitions, such as PRS (Precision Rifle Series). The cartridge is built to provide a balance between accuracy, barrel life, and manageable recoil, making it suitable for competitive shooting and long-range applications.
One distinguishing feature of the 6MM GT is its case design, which is optimized for consistent velocities and efficient powder burn. It typically utilizes small rifle primers, which help in producing a more uniform ignition and enhancing the overall consistency. The cartridge can be loaded with high-BC (ballistic coefficient) 6mm bullets, which are favored for their stable flight and reduced wind drift over long distances.
The 6MM GT has garnered attention for its ease of loading, minimal case stretching, and reliable performance, making it a popular choice among precision shooters and handloaders seeking optimal performance from a 6mm cartridge.
Use cases primarily include competitive shooting and precision target shooting, but it can also be utilized for varmint hunting due to its accuracy and mild recoil.
