#3220 - 450 Bushmaster Brass
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 caliber 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 caliber. This cartridge utilizes the common .452" diameter bullet; reloaders can use bullet weights anywhere from 160–350+ grains.

If you are looking for quality and consistency, look no further, Starline has economical, consistent quality cases for you. I started 44 years ago with Starline Brass. This is great Brass.

I have used several different brass calibers from Starline Brass. The 450 Bushmaster is top notch and runs well in my AR platform rifle. I've reloaded several of the brass 8 times for working up loads and still no problems! I will buy again!
