I wish I could remember where and what caliber I got the brass in. A friend gave it to me I’m sure. Those primer pockets and the military crimp issue were time consuming problems. Now I need to shoot more to necessitate reloading more, so I can remember more. I truely learn how much I don’t know about things as I continue to do them. Have you noticed there’s not much brass left on the range anymore? If it’s laying there and reloadable brass I pick it up. Tumble it then see if I have anything it works in.
