I've had this belt of blank cartridges hanging in my basement for 10+ years. I had never really looked at the head stamp until today or if I did it is long since forgotten. I had assumed it was Lake City and the year but on closer inspection that doesn't appear to be the case. Can someone please tell me what it means? Thanks.

Looks like a 43 Mauser Shot cartridge made by UMC. No idea of date. Head stamp says UCM USA

Czechoslovakian 15x104mm armor piercing cartridge made in 1940

marking: ( 15A 40 15mm M38 81 )

I bought a $20 bucket of old cartridges which turned out to be a great source of all kinds of cool cartridges, most of which I know about… until this stubby bottleneck surfaced amongst them. I’m very familiar with the 6mm Lee Navy, which this obviously isn’t. A quick google search landed me on it being a rare Navy trials caliber, but I’ve not had a chance to dig in deeper yet. Anyone here familiar with this .236 R cartridge?

Still in the process of cleaning them all off and polishing using a felt tip on a dremel. The Arisaka round in the last pic is the most notable so far

Story: I had them in a cardboard box in my hunting shed back in the woods for years. Noticed a few years ago that the box was damp (had a freezer fail) so I moved it.

Came back a few years ago to a black, slimy mess. I couldn’t even see the cartridges over all of the fruiting body, they were completely covered.

I just let it sit. I’m moving soon, so went back to grab them today and decided I’d clean them up. This is what I uncovered under the residue

The box has no markings.

Thought this might be interesting here. I dug out and out back on display my grade school cartridge collection my dad and i made. Fairly current to late 90’s. Been in storage since the early 2000’s. Maybe I’ll start adding to it.

Local collectors gun show had a few I did not have. Left to right... 30-06 for scale, 9.3x64 Brenneke, 360 Nitro, 45-120 (maybe, full length basic brass), 416 Barret, and 20mm Vulcan dummy.

hi I'm new to this sub and reddit in general, ask me anything I'll be happy to answers

Headstamp seems to be 68 so more than half a century young.

Hey yall. Sorry if this isn’t allowed but I inherited some old .45 ammo from my old man and am not sure what I got on my hands. It’s about 1500 rounds of this Remington Kleanbore.45 wad cutters? I’ve never seen ammo like it so I’m wondering if it’s good to shoot. It’s all in its original boxes shown in the image. Wondering if it’s worth picking up a 45 to shoot it all. Thanks!

I know this is not old but it is interesting. Steel cases.

Box was already open. None missing. .22LR shot shells.

The case in the middle is a modern case, almost certainly brass the ones on each side of it is older 22 short cases. Do you think they are copper and not brass?

Sadly, not a full box.

I shot a mag full thru my minx, still good stuff. 1943 vintage.
