Nosler 340 WBY Premium Brass (25ct)

Nosler 340 WBY Premium Brass (25ct)

The Nosler 340 WBY Premium Brass (25ct) is engineered to provide handloaders with match-grade cartridge cases that deliver consistency, power, and reliability. Manufactured from premium-grade brass to Nosler’s exacting standards, each case is fully prepped—trimmed, chamfered, deburred, and annealed—making it ready for immediate use in rifles chambered for the 340 WBY cartridge.

Designed specifically for the 340 WBY platform, this brass features uniform neck wall thickness, concentric neck geometry, and precise head dimensions. These specifications ensure consistent internal volume and controlled chamber pressure—critical for creating high-performance big-game loads or heavy hunting rounds. The clean primer pockets and flash holes support dependable ignition and tight velocity spreads across repeated reloads.

Nosler’s annealing process reinforces the neck and shoulder areas to preserve proper neck tension and reduce springback, even after multiple use cycles. Whether you’re developing heavy, long-range hunting rounds or hunting-specific loads, this brass offers reliable bullet seating and secure chamber fit for the 340 WBY cartridge. The structural integrity ensures predictable pressure behavior when using brass in this caliber.

Packaged in a 25-count box, Nosler 340 WBY Premium Brass is compatible with all standard reloading dies and equipment for this caliber. The factory-prepped condition eliminates the need for trimming or chamfering, saving reloaders valuable time at the bench. Dimensional uniformity and match-grade consistency make this brass a trusted choice for serious shooters working with the 340 Weatherby cartridge.

Each production batch undergoes rigid quality control to ensure consistent metallurgy, case wall strength, and headspace tolerances straight from the box. Reloaders will appreciate reduced case-to-case variation and improved alignment during seating—resulting in tighter groupings and improved accuracy downrange with 340 WBY ammunition.

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 340 WBY cartridge.
