Peterson Cartridge
Peterson Cartridge 300 Weatherby Magnum brass is engineered for reloaders who demand consistency shot after shot. The 40003-R 50/10 package gives you 50 pieces of unprimed rifle brass—ideal for building a matched ammunition lot for hunting, competition, or precision range work. Peterson's match-grade brass is produced in small batches with rigorous quality oversight, so every case meets the same exacting standard from the loading bench to the target.
If you're working with a 300 Weatherby Magnum rifle, this brass forms the foundation of reliable, repeatable handloads. Match-grade consistency means tighter velocities, more predictable trajectories, and better group density—especially important when you're dialing in loads for long-range hunting or pushing precision at the range. Peterson's attention to the entire manufacturing pipeline translates to casings that perform uniformly through multiple reloading cycles.
The 50-case quantity is a practical size for testing loads, building a new lot, or topping off your reloading inventory without overcommitting to a larger quantity. Whether you're a dedicated handloader seeking premium brass or a hunter refining ammunition for your magnum, Peterson's match-grade standard delivers the consistency you need to shoot your best.
