Name that cartridge!

[BrentD]

You’re incredible close to the actual head stamp.

.22-15-60 UMC

I actually found one of these in the field and had to research what it was.

Stock google photo as I can’t find the actual cartridge at the moment.

yes I knew the full name, but like tha .45-70-500, we usually leave the bullet weight off as it is highly variable. I have never seen one. I think they would be very cool critters, but what to do with one? So many fascinating cartridges that I just can't think of what I would do with them. This is one of those. That you found one in the field is amazing. Have you found a rifle to go with it?

I found it interesting that the head stamp has the -60 on it. It’s a cool piece for sure. Looks like a .22 hornet stretched WAY out or a 40-70 sharps straight that went through the dryer.

I’ve never seen a rifle chambered in it but it was offered in the Stevens 44 at one time in history.

4mm maybe 4.5mm caliber, case length 2.25", rim diameter .309"

Close as I can get is something based on the 57mm SPIW round.

It's the xm645. Dad was thinking it was a cast bullet but it's the sabot. It's got an IVI 69 headstamp.

Resurrecting this thread after a trip to my smith today. Pay no attention to the reamer specs. That is a .300WinMag next to them for reference.

.416 Barrett?

Son of a… well, that was short-lived. You are correct.

I got lucky…. I own a .50 bmg so it helped me guess.

Was going to ask if you presently happened to have a .416 being built down in the Springs. Good call!

 

[Cogreeny]

I would like a .416 but opted for the .50 for the availability of ammo. It’s the most unpractical rifle ever but it’s fun to shoot rocks a loooooong ways away. Fun conversation piece as well.

Our governor decided we aren't allowed to have one.

Looks like the statute specifically prohibits only rifles chambered in .50 BMG. So, @p_ham... .50 BMG-AI?

Sounds like a will not comply situation and a road trip to Indiana to me.
