The Peterson Cartridge .25 Weatherby RPM Bulk "Shooter Pack" delivers 250 premium, American-made unprimed rifle casings engineered to handle the modern, non-belted, rebated-rim geometry of the Weatherby Precision Magnum chassis. This high-volume pack bypasses individual plastic retail dividers to deliver maximum economic value to dedicated handloaders, while strictly maintaining the exceptional case-to-case weight consistency and strict wall-thickness uniformity Peterson is known for. Drawn from premium brass alloys on state-of-the-art production lines, each casing features optimized internal volume distribution and enhanced structural hardness that prevents head expansion and preserves primer pocket tension over multiple reload cycles. Arriving fully annealed and ready for the reloading bench, this bulk components group eliminates the variance of mixed brass lots, enabling hunters to confidently build uniform, high-velocity hunting cartridges capable of sub-MOA precision at extreme ranges.
