Quick Note on 7.62x39 Brass...

[Full Clip]

I've started to see a lot of MFS brass showing up in the once-fired lots I've bought on Gunbroker (and it seems pretty okay quality, about like PMC), but also an annoying amount of Berdan-primed Yugo surplus brass, which is, of course, not reloadable. (Not easily at least, by most of us.) So if you're bidding/buying on x39 brass, make sure the seller has checked this stuff out. Some just collect and sort by caliber and don't really inspect for Berdan/Boxer, especially as virtually all previous brass x39 has been Boxer.

I have noticed that some also could be large or small primer. Kinda weird but I have run into that at times

Small primer x39 is almost always going to be older R-P brass.

Yeah, I have a stash of the R-P brass... works fine.
