I've got 211 pieces of 300 BO brass I don't need. I had thought of getting a AR for it, but decided not to. It is all range pickup. They are deprimed and SS tumbled. There are 15 that are 223 head stamped but the others are all 300 headstamped. 2 of them look like they've been stepped on but should resize okay. $25.00 shipped. If you think the price is too much, shoot me a price.
