Ray, are these military brass? they had what I believe was a Berdan, or something like that, primer. It does not have one center hole, but a couple smaller holes. You can not de-prime these the normal way. They do make special equipment to de-prime these, but you need the rest of the reloading gear to go with it. I have a piece of 2X4 with a hole just a bit bigger than the cartridge about 1/8 in. deep with another hole centered in first hole thru the wood just a bit bigger than the primer. I set the brass upright in this and with the smallest punch in the Harbor Freight transfer punch set, knock them out with a couple light taps with a hammer. No problem, until I came across a couple military rounds. If the brass has a date on the head stamp instead of a brand name, probably military. Hope this helps.
