I was at the recycler today looking for lead and looked into a brass bin to see a whole bunch of 40 S&W and 223 brass. That is not odd in itself but the brass was nickel and had a purple tint or wash on it. I thought it may be steel but it is non-magnetic and was in the brass bin.
It is boxer primed, but the primers on the 223 are crimped.
Head stamp on the 40 S&W is WMA 15 and in addition to the "223 REM" markings, the later has "WIN 16".
What is this stuff? I am assuming from the amount of it, it must be Law Enforcement that is generating it.
Inquiring minds want to know...
