Weatherby .257 Magnum Unprimed Brass 20/Box

Premium Reloading Brass for the .257 Weatherby Magnum

Weatherby's unprimed brass offers reloaders the foundation for consistent, high-quality ammunition. Each box contains 20 cases manufactured to exacting standards.

Key Features

• CNC-Machined Primer Pockets — Precision-engineered for reliable ignition and consistent seating
• Match-Grade Specifications — Strict quality control ensures uniformity across the lot
• Norma Precision Manufacturing — Time-tested brass formulation for durability and longevity
• Annealed Construction — Heat-treated for optimal expansion and contraction during firing, ensuring secure bullet retention

Preparation Before Reloading

Weatherby brass arrives ready for the reloader's bench, but proper preparation is essential. Before loading, cases should be:

• Sized to ensure consistent dimensions
• Deburred to remove any sharp edges from the case mouth
• Chamfered to prepare the primer pocket

Note that the manufacturing and shipping process may result in case mouths that are not perfectly round. Additionally, the annealing process may leave a slight stain near the neck—this is normal and does not affect performance.

The Reloader's Choice

Popular among serious handloaders and game hunters alike, this brass provides the consistency needed for precision shooting and reliable field performance.
