Product Overview

Built for shooters who demand consistency, Peterson 300 Wby Casings are match‑grade brass designed to keep your Weatherby running hard and hitting true. Every case is produced in small batches, then checked and re‑checked so you get uniform wall thickness, tight primer pockets and reliable neck tension. That means smoother chambering, more predictable pressures and tighter groups downrange. Whether you’re building a long‑range hunting load or stretching things out on steel, this box of 50 unprimed cases gives you a rock‑solid foundation for repeatable performance. From the press to the paddock, Peterson’s focus on accuracy and durability lets you spend less time sorting brass and more time sending rounds exactly where you want them.
