Weatherby Unprimed Brass Rifle Cartridge Cases 20/ct .257 Wby

These cases require sizing, deburring, and chamfering before reloading to address potential mouth irregularities from manufacturing or shipping. The annealing process applied during production enhances the brass's flexibility by controlled heating and rapid cooling, which may leave slight discoloration near the neck but improves bullet retention and case longevity.
