Most Obscure Caliber?

[ronstafari]

The more I learn about firearms, the more often I stumble upon calibers I'd never seen or heard of. What are the most obscure caliber firearms you all own? This is a good opportunity to educate your fellow Calgunners about what's out there!

I actually have a box of ammo for that Dog. I always wondered what gun that ammo would fit in.

The ammo is worth more than most of the pistols.

For me it's 7.62x38mmR Nagant.

.45 GAP comes to mind for recent production calibers

2mm pinfire, probably. Actually, any pinfire caliber.

8mm Siamese Mauser - 8x52R but not the same as the more common 8x52R that you may know of.

You make these from .45-70 cases.

Also, 7.62x45 for the VZ-52 Rifle. You can make these from .220 Swift

[glassparman]

.22 LR

LOL PML - this is by far the winner!

2mm pinfire for me or, 7.5 Nagant for my 1887 Nagant revolver. Of course, it is also not easy to find 7.35x51.

I've started a collection of caliber examples in my garage. I'm up to almost 50.

Few months ago I came across a stash of ammo, at least 12 oddball calibers. 12 of them I had never heard of. Sold them all but kept one of each.
