ADG 300 Winchester Short Magnum (WSM) Brass is engineered to deliver the strength, consistency, and accuracy that reloaders expect from premium magnum cases. Built to tight tolerances, this brass supports reliable chambering, extended case life, and the uniformity needed for repeatable accuracy.
Made in the USA from premium cartridge brass, each ADG case undergoes a controlled hardening process that increases durability under magnum pressures. With precise neck wall thickness, consistent case weight, and concentric dimensions, reloaders can count on ADG 300 WSM brass for dependable performance in demanding shooting conditions.
This brass is designed for both consistency and durability. Additional material has been added in key areas to strengthen the case. As a result, ADG brass is heavier than most other manufacturers’ brass and requires lower charge weights to reach the same pressures and velocities due to reduced internal volume. We recommend using reputable published load data and always working up carefully from the minimum starting loads.
