Hornady Unprimed Brass Rifle Cartridge Cases .450 Bushmaster 50/ct

Hornady Unprimed Brass Rifle Cartridge Cases in .450 Bushmaster deliver the precision foundation serious handloaders demand. This 50-count box of unprimed brass cases provides the consistent case geometry necessary for match-grade accuracy in one of the modern era's most powerful lever-action calibers. Hornady's manufacturing tolerances ensure each case meets exacting specifications before you ever seat a primer or bullet.

The .450 Bushmaster cartridge delivers rifle-level power in a straight-wall platform designed for AR-15 platforms and lever-action rifles. Hornady's unprimed brass features tight wall concentricity, which ensures proper bullet seating alignment in both the case neck and your firearm's chamber. This geometric precision directly translates to uniform bullet release on firing—critical for the velocity consistency and group tightness that distinguish handloaded ammunition from factory offerings. Uniform case wall thickness, manufactured to Hornady's benchrest-grade tolerances, minimizes internal volume variation from round to round. This consistency reduces pressure spreads and improves shot-to-shot velocity, enabling the precision rifle shooters and hunters targeting large game to achieve repeatable ballistics downrange.

Handloaders working with .450 Bushmaster—whether for lever-action hunting rifles, AR-15 platforms, or precision rifle projects—benefit from starting with quality unprimed cases. The .450 Bushmaster chambering has gained traction among hunters pursuing medium to large game in jurisdictions requiring straight-wall cartridges, and among AR platform shooters seeking maximum stopping power in a common receiver. This 50-round brass case supply supports component builders who demand dimensional consistency and concentricity from their case stock.
