In the mud
I dug this in an area where I found a couple items from the late 1800's, so it may or may not be from that same time era. At first I thought it was just a 45-70 and put it in the "interesting" pile but when I started cleaning it I realized it isn't a 45-70.

I tried to match it up with other cartriges but it doesn't seem to match with anything I can find, I need some help on this one.

Rim Diameter-- .628"

Case diameter-- .505" (just above rim)

length--- 1.867"

Primer hole--- .17"

I measured the best I could (dial calipers) but consider there is slight corrosion build up and case diameter was taken near base due to mouth being deformed.

I can see no markings on it at all, I looked at it from every angle with the loupe and it appears to be unmarked :?:

Inside there is an unusually large hump where the primer is-- possibly an "Orcutt" primer ???????

Thanks, Rob
 
I cannot find anything with exact measurements. It looks to be a .50-70 of some sort. I almost think that it might be a .50-70 Rodman-Crispin, except the primer doesn't look exactly right. I am still looking though.

Can you get as accurate as possible case diameter measurement just above the rim and at the neck?

Thanks,
Doug
 
Hey Turtlefoot, I apologize, I missed typing in a "0".

Case dia. should be .505" just above the rim. The neck is so distorted I can't measure.

Again, I apologize for the miss-type, its been a long week with little sleep.

I understand the little sleep! My days have been starting at 3:45am for the last two weeks! I will do some more digging.

I am going to go with .45-60 Winchester. Here is the "standard" measurements for this shell.

Case Length - 1.89" (your measurement - 1.867")
Rim Diameter - 0.629" (your measurement - 0.628")
Base Diameter - 0.508" (your measurement - 0.505")

It's not exact with what you measured but it is VERY close

This is actually a good thing. I spent some time looking based on the earlier infor and didn't get a match. Will look again..maybe bit later (slightly intoxicated atm) ;) I have cartridge corner's full database so perhaps I'll get a hit.

Hmm it seems turtlefoot was faster..good choice but it might actually be 45-60 Wesson.
Both Winchester and Wesson made this cartridge but based on pic they are bit of different shape..will get back to this later

I too thought about the .45-60 Wesson, but figured it was a scarcer round and went with the one that was more common.

Good info Voriax!

Thank you so much guys!!

Once I had a name I was able to find this on the IAA Forum

His measurements for the 45-60 WCF in his collection are almost dead on with what I have!!!!! :yes:

I don't understand why there are no marking on the cartrige, unless it was VERY light and they are now gone :?:

Thanks again guys, I really appreciate it. I had looked and looked and couldn't come up with it myself.
