Weatherby Select Plus Features Weatherby Select Plus Unprimed Cases are manufactured with CNC machined primer pockets held to match grade specifications giving handloaders a consistent foundation for building precision .257 Weatherby Magnum ammunition. Because every pocket is machined to the same tight tolerance primer seating depth and ignition consistency improve from round to round which in turn tightens group sizes downrange. This level of case preparation is typically reserved for premium factory match ammunition and Weatherby extends it to its own brass line for handloaders who demand the same consistency from their reloads. The result is brass that performs predictably through multiple reloading cycles. Produced from brass and sold unprimed these cases are reloading components only and are not loaded ammunition ready to fire out of the box. Weatherby offers Select Plus Unprimed Cases across its full range of Weatherby Magnum calibers letting handloaders standardize on a single trusted brass source across their rifle collection. Fifty cases ship per box giving reloaders enough brass to work up and refine a load before committing to a larger batch. Precision rifle shooters and dedicated Weatherby Magnum handloaders will find this brass a dependable building block for their reloading bench.
