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.
In my experience, all of the Asian/European 6.5mm, 8 x 50R Austrian, 8 x 56R Hungarian, and much of European brass (except Norma)is Berdan primed.
Greek and Turkish 30-06 and 7.62 NATO can be Berdan primed
I have always picked up stray brass at shooting ranges.
I came across some 225 Win and 33 WCF that way, still have it, though no guns to shoot it.
Yes, I have hoarding issues with ammo. LOL
