Weatherby BRASS257 257 Weatherby Magnum Unprimed Rifle Brass 20/Box

The Weatherby BRASS257 unprimed case is built for handloaders working with the .257 Weatherby Magnum, one of the signature belted-magnum rifle cartridges in the Weatherby line. Each case is manufactured from Norma Precision Brass with CNC-machined primer pockets and produced to match-grade specifications for the tight, consistent tolerances serious reloaders demand.

The .257 Weatherby Magnum uses a belted-case design that adds strength at the case head and provides a repeatable head-spacing surface at the belt - features that handle the high pressures associated with magnum-class velocity. With Weatherby-branded brass, handloaders can build loads using the same case geometry that underpins Weatherby's factory ammunition, supporting predictable case life, consistent ignition, and tight neck and shoulder dimensions shot after shot.

Sold as a 20-count box, these unprimed rifle cases are ready for primer installation and handloading with your choice of appropriate primers, bullets, and powder. They are a natural pick for hunters and handloaders building magnum-class rifle ammunition around the .257 Weatherby Magnum.
