Starline’s 450 Bushmaster unprimed brass gives reloaders the foundation they need for this hard-hitting cartridge. Originally designed as a close-range, big-bore hunting caliber for the AR-15 platform, the .450 Bushmaster requires only an upper receiver swap for AR conversions. The caliber has gained significant traction with the introduction of new bolt-action rifles and recent changes to state game laws that now permit straightwall cartridges for deer hunting.
Ruger has embraced the .450 Bushmaster, chambering it in their American Ranch and Gunsite Scout bolt-action rifles. The cartridge accepts common .452″ diameter bullets, allowing reloaders to work with bullet weights anywhere from 160-350+ grains. This 50-count package of unprimed brass provides the versatility needed to develop loads across the full range of .450 Bushmaster applications.
