The Weatherby Brass 30-378 Weatherby Magnum unprimed cases are built for hand loaders serious about precision and consistency. These fired-once or once-fired quality brass cartridges give you a reliable foundation for assembling match-grade 30-378 WM ammunition, whether you're developing loads for a long-range hunting rifle, a competition shooter, or someone who just wants to control every variable in their reloads. Weatherby's reputation for magnum cartridge engineering extends to their brass, and these cases are manufactured to tight tolerances that reward careful handloaders who invest the time in load development.
What sets Weatherby brass apart is the attention to primer pocket machining. Each case features CNC-machined primer pockets engineered to match-grade specifications, which means they'll accept primers consistently and fire with the kind of shot-to-shot uniformity that matters when you're trying to ring steel at distance or hunt elk across a canyon. For reloaders who run volume through their presses, that precision adds up—tighter groups, fewer pressure surprises, and longer case life because uniform primer seating reduces the stress that can cause rapid brass fatigue.
This box contains 50 unprimed cases, giving you a full suite of components to start loading. Whether you're building a new lot for a rifle you just dialed in or stockpiling components for next season, starting with quality Weatherby brass means fewer variables to troubleshoot and more confidence in the final round.
| Caliber | 30-378 Weatherby Magnum |
| Product Type | Unprimed Brass Cases |
| Count | 50 Cases |
| Primer Pocket | CNC-machined, match-grade specifications |
These are unprimed cases. You'll need to source primers separately and install them as part of your reloading process.
Match-grade primer pockets are machined to tighter tolerances than standard pockets, which ensures primers seat with consistent pressure and uniformity. This translates to more predictable velocities and tighter shot groups in your finished ammunition.
Each case produces one finished round, so 50 cases will yield 50 loaded cartridges once you add primers, powder, and bullets.
