The Nosler Premium Brass .30-378 Weatherby Magnum, 25 Count (Nosler part no. 10235) is new cartridge brass that Nosler has already prepped for loading. Each case is chamfered, deburred, checked for proper alignment, sized and trimmed to proper length, then hand inspected so dimensions meet Nosler’s standards and tolerances. That prep work is aimed at shooters who want to take finding the perfect load into their own hands without spending bench time on case preparation. It is made in the United States from quality materials chosen for case life and reloadability, and it comes 25 to the box.
