Went out shooting last week and picked up some .223 "brass", kinda made my day. I didn't bother checking out the headstamp and just threw them in the .223 bucket. Today started to process some .223 and these wouldn't deprime, I put them aside and the growing pile started to piss me off. Although my detective skills aren't on par with some who are on GTR forum I think I solved the problem. At first it looked like a chinese symbol but turns out it's Russian (JSC Barnaul, Brown Bear). Brass washed steel and berdan primed.
