What cartridge is this?

Third from left.

Looks close to a 50-100, but diameter seems .577 caliber.
What's the neck measure and case length.
Does the base have a ridge on it, can't make that part out.

It isn't handy to me at present. The dome on the base was unique to me.

577 Snider but never have seen that dome on the base before. Must be an interesting breech block.
Unless the brass has decided to grow. Horrible thought but it’s many years old.

 

[5spd]

Looks closer to a Maynard round.
None of my 577 Snyder's have that type of rim.

See if it measures around 54 caliber. It may be a Burnside pre
civil war carbine cartridge.

Doesn't appear to have a primer pocket, so primer compound at base. And swelling from chemical reactions?

Copper cased it seems, may be internal primed, but I don't see 2 crimps on head of case like other internal primed cartridges.

Well it's not the Burnside after further digging......

I'm too dumb to get a link to post but it looks like a "Billinghurst-Requa" battery cartridge.

My first thought was, pressure???? But then I realize it hasn't been fired...those are some pretty grungy looking loads...

My overly trained eye for outstanding observations of the obvious tells me it is most likely maybe a very early Elmer Keith six gun cartridge. Back when dinosaurs were roaming north of Jordan MT.

 

[JMayo]

Well I'll be darn that is cool.
How and where did you get it ?

 

[butchlambert]

When Red Cornelison passed away I purchased a truckload of brass, bullets, primers and a multitude of firearm items.

 

[searcher]

Good job, FUJ!
Wish I had an ammo box full of those at $95.00 a pop!

This was part of Red's stuff. His business was engine repair from this one to huge industrial oilfield engines.This is a inboard boat engine from many days in the past.

From civil war battery gun cartridges to inboard boat motors. Red must have been the kind of guy to have gotten around!!! Sounds like his shop or barn or what ever could be a museum.

At home Red had a very large shop with very nice and newer mills, lathes, surface grinder, stock profilers, and much tooling. I bought a truckload of walnut stockblanks that were in the loft of his barn that were slabbed in 1956. The largest cartridges were 20mm. He had quite a bit of 50bmg loaded and brass. Some of you know, Red formed and loaded 17HMR many years before it was introduced. I have a few. I sold a case of 22mag RF primed brass that he used to a member here I think.
