NOT ALL BRASS MEASURES UP TO THE NOSLER STANDARD. AND THAT'S OK. THE WORLD NEEDS DOORKNOBS, BELT BUCKLES, AND FRENCH HORNS. Premium Nosler Brass: Fully Prepped, Ready To Load. Copper and zinc make it brass. Craftsmanship makes it Nosler Brass. We start with the highest quality material. We trim, chamfer and deburr it. We inspect it by hand. We weight sort it to within one-half grain. And only then do we put our name on it. What happens to the brass that doesn't make the cut? We're sure someone will find a use for it.
