Hey Guys, I was wondering if anyone know were 22 BR brass can be purchased if at all? If not, can I simply run 6mm BR brass into a 22 BR resizing die? Any help would be appreciated.

Excuse me, but I believe you are thinking of the .22PPC, not the .22 BR. The .22-BR is not made with ANY brass which has the case head diameter of the 7.62x39. It was originally made by necking down & shortening special Remington .308 cases which had pockets for small rifle primers, and were made of somewhat thinner brass. Some runs of that brass were even head-stamped .22 BR, but were still full .308 length.
I still have some of that brass, and an original full set of Neal Jones dies for converting and loading the brass.
Anyway, yes, one CAN easily make correct .22-BR brass by necking down the 6-BR or (more difficult, but not much more) necking down 7-BR cases. It pays to check the correct overall length of your chamber first, as in the early years of the .22 BR, some gunsmiths didn't cut their chambers the same lengths.
