I picked up some 7.62x39 "brass" the other day at the range that looked just like new Winchester brass. When I got home and ran my magnet through the bucket, I found it was steel with a brass coating....into the trash it went.Can you? Yes. Should you? Probably not the best idea. Is it practical to reload? No. Almost assuredly berdan primed. De-priming requires special tool. Finding proper size berdan primers is almost impossible.
