What do you think this cartridge fits?

Found this a gun show awhile back. I've never been able to figure out what it fits. It says 30CAL.

Any clues ?

;)

Looks kinda like a .308 with on of those Remington "accelerator" bullets in them. It's essentially a .22 caliber bullet in a plastic sabot to make it .308 diameter.
 
Not an accelerator, not a.22, certainly not a .30 caliber, and I don't even believe that it is a .308 win.

That has to be some outrageously nutso wildcat, it is probably a .257 diameter, it may or may not be based on a .270, I don't know of any standard non belted case big enough, off hand, to gain anything like this.

That thing is just nuts. I do seem to remember seeing it before.

Do us a favor. Whatexactly does that headstamp say, and why didn't you post a pic?:confused: put up a pic please.
 
looks like a blank round that had the folds straightened out and a bullet inserted in it.

Yes, it does, took me forever to locate a good photo to post. I started right after my previous post.

I don't think that it's an altered blank, probably not, but I'm still unsure what the check it is and why it was made.

A prank, or joke?

There is absolutely no rational reason for using two shoulders. It would probably even interfere with accuracy.
 
I would guess it's someone's idea of making a conversation piece. Maybe a double shouldered blank that was cut back and they seated a bullet in it. I can't imagine any other use for it.
 
It created a conversation here. I can imagine a dozen people standing around at a range having this same discussion, while the guy who created this chimera snickers inside of himself.

Really, I wasted well over a half hour contemplating and researching.
 
Ummm....
A blank doesn't have a 25 caliber ballistic tip...

It's just a showoff piece. Kinda like the Eargunsplittenloudenboomer...

I wasn't saying that the round supplied was a blank, that's absolutely ridiculous. I showed that as an example of a double shouldered round. Nothing else.

Triphammer, that explanation is probably right, the shapes seem correct. Special chamber, custom dies, painfully difficult case forming, all intended to turn a 25-06 into a half baked half crazy .257 Roberts class rifle cartridge.

I once met a guy who put a four barrel carburetor on his four cylinder Vega, it could be done so he bought a case of beer one weekend and did it.

This took a lot more work, but I think that the same principle was involved.

I've come to believe that whoever did this actually had the rifle made to go with it, but it's possible that the guy just sat in his shop and made the rounds.

How many dies, how many steps would it have taken to form those cases?
 
Looks like a conversation piece to me. The front shoulder is too sharp to be formed in a die, looks like it was soldered on to a .308ish case.
 
Years ago, someone gave me the ultimate "overbore" cartridge; what appears to be a .50 caliber case necked down to .17 caliber. It has what looks to be a live primer in it...:eek:
 
Haven't a clue?
Speculating_ Such color Tipped bullets I use when reloading for my 25-06. i.e. Ballistic {blue} tip nosler
Brass? of military sort.
 
Bob Hutton was a bit strange. Iirc, he also coined the term "UMAGGBEE" for about twenty grains of 2400 in any non magnum case above .22 diameter.

"Universal, makes any gun go bang." He proposed it as something that didn't really exist in principle at the time, a post-apocalypse asset. A keg of 2400 could load almost any rifle or pistol, and you could even do it by just taping a few labels on the keg that could load just about any round in the planet based on bullet weight, diameter, and case capacity.

The funny thing is that all of the loading data of the time pretty much supported it. The rounds would be terribly inefficient in some cases, but if it's a matter of roasted raccoon or pine bark for dinner, killing the coon will be more important than the powder used.
 
It must just be a conversation piece. I thought it was odd, that's why I bought it. It does appear to have a live primer and it. It has some weight to it so it's not empty but it doesn't feel like it would be full either.

I'm going to see my son this weekend, he is a marine veteran so he should have some idea what it is. I'll keep you posted as to what he says

Thank you all for your insightful responses. I apologize if some of you spent time better spent elsewhere looking for a unicorn .
