Peterson Cartridge
Peterson Cartridge 6.5-300 Wby brass cases deliver the volume and consistency serious reloaders need for magnum rifle ammunition. Whether you're building long-range hunting rounds or precision target loads for your weatherby, these unprimed cases give you control over every step of the reloading process. The 250-count bulk package is sized for shooters who work through brass regularly and want to minimize per-round component costs without sacrificing quality.
Peterson is known in the reloading community for consistent case dimensions and reliable quality control—details that matter when you're chasing tight shot groups or developing loads for hunting. Working with Peterson 6.5-300 Wby brass means less prep time sorting and measuring, more time at the range testing your loads. The bulk format makes sense if you're stocking up for a season of shooting or building ammunition for multiple firearms in the same caliber.
Reloading your own 6.5-300 Wby ammunition lets you tailor velocity, bullet weight, and powder charge to your rifle and hunting conditions. You'll also recoup component costs over time compared to factory ammunition, especially if you're a high-volume shooter or competitive marksman who fires hundreds of rounds annually.
| Brand | Peterson Cartridge |
| Caliber | 6.5-300 Weatherby Magnum |
| Type | Unprimed Brass Cases |
| Quantity | 250 cases |
| Part Number | 40059-P |
Unprimed cases come without a primer installed. You'll need to use a priming tool to seat primers into the primer pocket during your reloading process. This gives you the choice of primer type and brand based on your load requirements.
Peterson 6.5-300 Wby brass is designed to work with standard reloading dies and equipment for this caliber. Always verify your die and sizing equipment specs with the manufacturer, and perform a test fit with a sample case before processing a full batch.
Case lifespan depends on your specific loads, powder charge, bullet weight, and rifle. Peterson brass is built for consistent performance and durability, but the number of reloads varies by shooter. Proper case inspection, trimming, and storage practices help maximize case life.
That depends on how much you shoot. A 250-count box is a good starting point for hunters who fire 50–100 rounds during preparation and the season itself. High-volume shooters or those testing multiple load variants will want to consider additional quantities.
