6mm GT

Caliber Overview
The 6mm GT, short for 6mm Grey Tiger, is a highly regarded wildcat cartridge developed around 2018 by gunsmith George Gardner for GA Precision. This cartridge is based on the 6mm Creedmoor case, offering enhanced performance for long-range precision shooting. Primarily used in competitive shooting, varmint hunting, and tactical applications, the 6mm GT delivers exceptional accuracy and ballistic efficiency. At AmmoSouth, we stock high-quality 6mm GT ammunition from trusted brands, making it a go-to choice for enthusiasts seeking reliable options for precision-focused activities.
Key Specifications
The 6mm GT features a bullet diameter of 0.243 inches (6mm), with typical grain weights ranging from 105 to 110 grains for optimal balance of velocity and stability. It produces mild recoil, comparable to the 6.5 Creedmoor, making it manageable for extended shooting sessions without excessive fatigue. Ballistically, it achieves muzzle velocities up to 3,200 feet per second, with an effective range exceeding 1,000 yards due to its flat trajectory and minimal wind drift. Compatible firearms include custom-built rifles from GA Precision, as well as platforms from Ruger and Remington that can be chambered for this cartridge. At AmmoSouth, we ensure our 6mm GT selections are tested for compatibility and performance.
Applications
This caliber excels in competitive shooting disciplines like PRS (Precision Rifle Series) and F-Class, where its long-range capabilities shine. It’s also ideal for hunting medium-sized game such as coyotes and deer, thanks to its precision and energy transfer. In tactical scenarios, the 6mm GT provides reliable performance for law enforcement and military marksmanship training, offering a versatile option for both recreational and professional users. AmmoSouth carries ammunition tailored for these diverse applications, ensuring shooters have access to top-tier products.
Ammunition Types
