Starline Brass Cases Cal.: 450 Bushmaster

  • 1.693 - 1.697 O.A.L. 
  • The 450 Bushmaster was designed as a close range, big bore hunting caliber for the AR-15 platform. As with most AR cartridge conversions, it only requires swapping out the upper receiver. 
  • With the introduction of some new bolt action rifles in this calibre and many states changing game laws allowing straight-wall cartridges for deer hunting, the .450 Bushmaster is enjoying a surge in popularity. 
  • Ruger now offers their American Ranch and Gunsite Scout bolt action rifles chambered in the .450 Bushmaster calibre. This cartridge uses a small rifle primer and utilizes the common .452" diameter bullet, reloaders can use bullet weights anywhere from 160-350+ grains.
