Mine is a bit of a mix too. It seems to have a home made firing pin, or one that was modified. But it does work. I put some pics of my extractor repair in the gun smithing forum.

Here is my navy carbine.
Lol - they are sweet. At 62, I'm getting to the point where I appreciate lighter recoil. The .50-45 is more comfortable than my .50-70s.
Coincidentally, the same cartridge runs in my centerfire model 1871 Springfield Spencer 2 band rifle. This rifle has a longer chamber than earlier Spencers. It took a lot of trial and error to figure that out.
I really enjoy mine. I am the original thread starter It took me awhile to figure out where it was shooting. But it was my first black powder cartridge.
I know mine is not original but I would like to figure out what it was before it was a carbine.
1) A Navy barrel and a Springfield receiver? I thought I understood that threading these barrel never aligned the same between two receivers.
2) A cut down rifle. But how did it get that chamber?
3) There was a few army rolling block carbines but they had a longer forearm. I really doubt this.
here is my ancient remington roller #1-1/2 .45-70 that may get rechambered in .32-20 and "carbine-ized" ...
Can you post some good photos of your carbine, and any marks? Does it have the concave or flat breech block? Original navy carbines had the concave block. I'm pretty certain that my barrel is an original navy carbine barrel. It has a nice anchor over the chamber. It also has the original carbine rear sight. The action is a later type with the flat block ground to work with the barrel.
It has a Springfield m1868 rear sight. This was probably taken off the original barrel removed from that action. Do you have Hosmer's book on .50 and .58 cal Springfield rifles? It is a great resource. Yours looks similar but not the same as the model 1870 Springfield experimental carbine.
WOW! KILLER ROUNDS. I want some of them to shoot in my REM. RB. CARBINE.
I have one built up on a 43 Spanish action using one of the Dixie surplus Navy barrels. My favorite load uses 5744 and the Lyman 515139 350 grain bullet in 25:1 alloy. 40 grains of Swiss 1 1/2 has worked well too. The cases are trimmed to 1.30" from 50-70 brass. Maybe both are called 50-45s but the 50 Springfield Cadet and 50 Navy carbine cartridges are slightly different in length, the Cadet being a little longer.

what load of smokeless powder load can I use in my 50/45, REM. carbine?
I'm generally not a fan of smokeless in these early rollers. That being said, if you don't want to use black powder, I think Blackhorn 209 black powder substitute is a good compromise. It is essentially a bulk smokeless powder with a smoke agent added. It is non corrosive, clean burning and very accurate in many of my old rifles. The only downside is the price, but its worth it to me. My .50-45 will shoot under 2" groups at 50 yards using 27.0gr of BH 209 and Rapine 350 bullet.
If the gun is truly an original, real black powder only would be how I'd load for it.
For modern steel cartridge guns that can handle smokeless, such as a Henry S/S in .45-70, I load AA5744 smokeless powder as it is designed to work in these kind of guns, but with no fillers or wads or compression, and works well with very loose powder loads.

what load of powder do you use, in the 50/45, BP, or SMOKELESS? I have a NAVAL CADET RIFEL, that I want to shoot. is there any other case that can be used rather than a 50/ 70 cut to length? thank you.
I'm glad that you had good fortune figuring out what you RB is...mine has been driving me nuts trying to cipher what it is!
Any idea of a price range they have seen those old 50 carbines (rolling block) for sale?
