I was looking to do an AR in a different chambering than 223/5.56. So I pulled up the list of options for an AR and noticed 7.92x 33 Kurtz. My partner says no the brass is to hard to find and too expensive can it be formed from something common? I haven't looked at the chamber/brass prints but uses the same bolt face as 06/308 ect ect. Can it be that easy?
