Weatherby BRASS303 30-378 Weatherby Mag Unprimed Brass Rifle Cases 20/Box

The Weatherby BRASS303 is a set of premium unprimed brass cases purpose-built for the 30-378 Weatherby Magnum rifle cartridge. Produced by Weatherby using Norma Precision Brass, these empty cases feature CNC-machined primer pockets produced to match-grade specifications, giving handloaders a consistent, high-quality starting point for assembling magnum loads.

Designed specifically for the dimensions of the 30-378 Wby Mag, each case is sized to magnum specifications. The unprimed format gives the reloader complete control over primer selection, case preparation, and load development. Some cases may exhibit minor cosmetic discoloration from the manufacturing process - purely aesthetic and not indicative of any functional defect.

This listing includes 20 unprimed brass cases per box, manufactured from brass and engineered to Weatherby's tight tolerances for reliable feeding, consistent ignition, and repeatable accuracy. Primers, powder, and projectiles are not included.
