The Nosler 300 WSM Premium Brass (25ct) offers reloaders a fully prepped, match-grade cartridge case designed for precision, consistency, and long-term durability. Crafted from premium brass to Nosler’s exacting specifications, each case arrives trimmed, chamfered, deburred, and annealed—ready for immediate loading without any additional preparation.

Engineered specifically for the 300 WSM platform, this brass features uniform neck wall thickness, concentric neck geometry, and precise head dimensions. These attributes support consistent internal volume and controlled chamber pressure—essential for developing flat‑shooting hunting loads or match-grade rounds in rifles chambered for the 300 WSM cartridge. Clean primer pockets and flash holes promote dependable ignition and tight velocity consistency.

Nosler’s annealing process enhances the neck and shoulder areas to maintain proper neck tension and reduce springback through multiple reload cycles. Whether you’re working up lightweight varmint rounds or heavy premium projectiles, this brass provides consistent bullet seating and reliable chamber fit. The structural integrity supports predictable performance downrange when using 300 Win Short Magnum cases.

Packaged in a 25-count box, Nosler 300 WSM Premium Brass is compatible with all standard reloading dies and equipment for this caliber. Factory-prepped cases eliminate the need for trimming or chamfering, saving reloaders valuable time at the bench. Match-grade dimensional uniformity makes this brass an excellent choice for precision shooters and high-volume handloaders alike.

Each production lot undergoes rigorous quality control to ensure consistent metallurgy, wall thickness, and headspace tolerances straight from the box. Reloaders will benefit from reduced case-to-case variation and better seating alignment—translating to tighter groupings and improved accuracy downrange with the 300 WSM cartridge.

This is a brass component only and is not loaded ammunition. It does not include bullets, powder, or primers. This brass provides serious reloaders with a dependable, high-quality foundation—ideal for maximizing accuracy, consistency, and performance with the 300 WSM cartridge.
