Unknown cartridge conversion

[Tubac]

Hi fellas, new guy here.
This does not apply to Spencers per se, but I noticed discussion of old cartridges on the Cimmeron post.
I have an original Rogers & Spencer revolver, that has been converted to center fire cartridge.
The back quarter of the cylinder has been removed and replaced with a machined plate to accomidate
cartridges.
The cylinder bore is .438" and 1.51" in length. This is too narrow for a .44 Special, or a .44/40 amd I would guess the .44 colt and .44 remington. A .41 magnum case fits fine.
Does anyone have any idea what cartidge was used in this pistol?
Thanks for your help and thanks to Two flints for letting me post this.

For the hell of it - try a .41 Colt - either Long or Short.

They were an outside-lubricated, heel-based bullet with a nominal diameter of .410.

You 'can' reload for them - but you've got to want to...

Vaya,

Tubac,

It sounds like a 44 S&W American.  My references show that this cace can be made from 41 Magnum cases.  According to the references, the original had head & base diameters of 0.438" to 0.440", used a 0.434" diameter, outside lubricated, heeled bullet and the overall loaded cartridge length was 1.440" to 1.460"(depending on which reference you use).  It is said to have been developed and introduced in 1869 which would make it a prime candidate for a cartridge conversion.

Hope this helps.

Thank you Hell'er High Water, may I ask what references you're using?
Right now, I'm opening up a .41 magnum case and using an outside lubed .428, backed by 20 grains of FFFG.
I'd like to see what the references say.
thanks again,

Tubac,

My primary reference is "The Handloader's Manual Of Cartridge Conversions" by John J. Donnelly.  My secondary reference is "Cartridges Of The World" by Frank C. Barnes.  In most cases they agree very closely with each other.

Both are good books to have in your library.

Just as a note, does this revolver have a rimfire hammer? There were some R&S's converted to .44 Rimfire and they went West. There is one in the Cody Museum. As a side note, it has now been documented that some (albeit few) R&S revolvers were indeed used during the Civil War. There was one a while back on an esteemed auction site with provenance.

The hammer has been modified as it is a centre fire.
I'm amazed at the number of responses, and I'd like to thank you all for your help.
