The 300 Weatherby Magnum is one of the most powerful commercial .30-calibre cartridges available, built around Roy Weatherby's distinctive belted case with its double-radius shoulder — a proprietary headspacing design that requires chambers cut to Weatherby dimensions. It pushes heavy .30-calibre bullets to very high velocities, making it a capable choice for long-range hunting of large and heavy game. Hornady's unprimed 300 Weatherby Magnum cases allow owners of Weatherby and compatible rifles to handload this demanding round on a quality brass foundation, rather than rely solely on factory ammunition. Each case is drawn and formed to Hornady's tight production tolerances, with wall thickness, concentricity and internal capacity all controlled closely across the lot. Consistent internal capacity is particularly important in a high-capacity case like the 300 Weatherby Magnum, where small variations in case volume can translate into meaningful pressure differences. Hornady applies a pressure calibration test during manufacture to confirm uniform case expansion, and the brass is constructed to yield multiple reloading cycles from each case.
