Weatherby .300 Magnum Unprimed Brass 20/Box

Premium Reloading Brass for the .300 Weatherby Magnum

Weatherby's unprimed brass represents a serious choice for handloaders who demand consistency and reliability. Manufactured from Norma Precision brass and finished to match-grade specifications, these cases are engineered for accuracy and longevity.

Key Features

• CNC-Machined Primer Pockets — Precision-engineered for consistent primer seating and reliable ignition
• Match-Grade Specifications — Strict quality control ensures uniformity across the lot
• 20 Cases Per Box — Convenient quantity for serious reloaders
• Norma Precision Brass — Proven quality from a world-class ammunition manufacturer

Important Preparation Notes

Before reloading, cases require standard preparation:

• Sizing and Deburing — Resize cases to proper dimensions and remove burrs from primer pockets
• Chamfering — Chamfer case mouths to ensure proper bullet seating
• Inspection — Check for roundness; manufacturing and shipping may affect case mouth geometry

You may notice slight discoloration near the neck. This results from the annealing process—controlled heating and rapid cooling that gives the brass its flexibility and ensures secure bullet retention. This is normal and does not affect performance.

The Reloader's Advantage

These cases are built for shooters who understand that precision begins with quality components. Whether you're loading for hunting or target shooting, Weatherby brass delivers the consistency that separates good groups from great ones.
