Peterson Cartridge's 6mm GT brass is engineered for reloaders who demand consistency from case to case. This 50-round pack of match-grade rifle brass is sized right for competitive shooters and precision hunters working up loads for the 6mm GT platform. Peterson's small-batch production and rigorous quality control mean less sorting and prep work on your bench—more time shooting groups that count.

The 6mm GT is a relatively new cartridge that's gaining traction in precision rifle circles, and Peterson's commitment to match-grade standards shows in case uniformity, wall thickness, and primer pocket concentricity. Whether you're building ammo for competition or fine-tuning a hunting load, consistent brass is half the battle toward repeatability downrange.

One critical detail: Peterson's SRP (small rifle primer) 6mm GT brass features a 0.060" flash hole—smaller than the 0.080" found in large rifle primer cases. This means you'll need an X-small or undersized decapping pin when resizing and depriming. If you're new to reloading the 6mm GT or swapping from another cartridge, factor that into your setup. It's a one-time tool investment that ensures clean, efficient depriming without damage to the case.
