Found a few of these yesterday while out hunting, what the heck are they? Some sort of industrial tool cartridge?

They appear to be belt-fed rimfire-type and looks like .17 caliber on the business end:

Brass Tool accessory Metal
Brass Finger Hand Metal Button
Finger Hand Nail Thumb Ear

Looks like some kind of sub caliber device that accepts a primer and a .177 pellet and will feed through a magazine. I dont understand the off center primer strike, though.

A homemade "reducer"? For plinking with your kids in a real rifle without too much recoil maybe?
It looks like it could shoot a .17 caliber rimfire in a .30-06
"Instickspatron" like the one below is used here for firing .22LR ammo in shotguns to kill small fur animals caught in traps that catch the animals alive

The rimfire primer is made by Eley. What chamber could that possibly fit? It's not an insert, not for any normal rifle. I thought it could be a custom fleschette cartridge but still, for what gun? Can you tell what caliber the top parent case is.

You don't USUALLY throw those things away... A typical reducer thingey like that may well run $20-100 each...

That sucker looks like a 223 shell reducer that shoots rimfire...

Poke the shell back out and find out what's in it... 17 HM2?

I bet there are some poachers hunting at night... That's how they stay quiet...
