Just went to my outdoor range yesterday. My out-of-the-ordinary finds were 32 ACP, 44 Magnum, 44 Special, 6.5 Creedmoor, and a dozen or so of what I believe is a Turkish rifle cartridge, maybe a Mauser. Leastways that's what a brief Google search turned up. Headstamp has a T, then a crescent with a star over it, then a C. Date 1942. Don't remember the rest of it, not that easy to read. Probably Berdan, but I just chucked it in a box to look at later.

The Creedmoor and 32 are headed for trade here, once I get enough to even list. The 44s are like gold nuggets to me, they aren't going anywhere.

Also found a few dozen 45 ACP, which is not that common, for that range at least. 38 and 357 are pretty rare too.

About half I find is steel case. I want a bumper sticker that says, "Friends don't let friends shoot steel case!"
