Whether you're precision-tuning for long-range hunting or developing match loads, starting with quality brass from the cartridge originator ensures dimensional consistency and reliable performance.
Weatherby's 257 Wthby Mag brass is manufactured to the exacting standards you'd expect from the company that developed the cartridge. Unprimed cases arrive ready for your bench: you'll prime, charge, and seat bullets according to your proven load data.

Each box contains 50 cases, a practical quantity for developing and testing loads, or for shooters planning a dedicated session at the bench. Proper case maintenance—cleaning, deburring, and inspection before loading—will extend case life across multiple reloads, making quality brass a smart investment in ammunition economy and consistency.
