Peabody Cartridges

I have a large list of “Peabody” cartridges:

9.6 x 60R Peabody
.40-70 Peabody
.40-90 Peabody
.44-95 Peabody
.45 Turkish Peabody (11.43 x 41R Turkish)
11.43 x 59 Turkish Peabody
11.43 x 59.94 Japanese Peabody
11.43 x 41R Turkish Peabody
.45-50 Peabody
11.43 x 60R Romanian Peabody
11.43 x 49R Romanian Peabody
14.66 x 35R Serbian Peabody
15.5 x 35R Serbian Peabody
.43-77 Peabody
.58 Serbian Peabody

I know Henry O. Peabody designed an early breachloading firearm (1862) that was used by several militaries. They were chambered for some common calibers (such as .45-70). My question is: what are the “Peabody” calibers? Were they cartridges designed by Peabody himself? Or were they designed by the military that adopted the rifle? If they were designed by the adopters of the rifle, why were they special calibers designated Peabody, and not just a standard designation, such as .45-70 or .43 Spanish, or 10.4 mm Swiss? Was there something unique about the “Peabody” cartridge design that made it only usable in a Peabody action?

Good questions.
I apologise in advance, because I am a huge fan of the Peabody & Peabody-Martini rifles!

What little I know about Peabody cartridges is what I learned by studying the rifle design.

In addition, I find no reference to Peabody cartridges in my 1965 “Cartridges of the World”, and at least one in “Handloaders Manual of Cartridge Conversions”: the .44-60 Peabody Creedmore, which is proprietary, and I suspect the others that carry his name are also.
They are listed by caliber, so it will be a time consuming search. If I find others I will let you know.

The first cartridge Peabody developed for the his rifle was his .44-40-50 Peabody Rimfire, about 1862~1863, and in 1866~1867 Canada contracted for some 5,000 rifles which were chambered in his .50-60 Peabody Rimfire, but only about 3,000- likely much fewer- were delivered.
The Swiss ordered them in .41 Swiss Rimfire, (Patrone M.67 10.4mm), Romania ordered 30,000 in 11.4x49R Romanian Peabody, (11.4mm Cartus Md. 1868), Spain got some 35,000 in .50 Spencer, and another 10, 000 in .43 Spanish, (11x58R Remington), in 1870, and Mexico received 8,500 of the same model/caliber.
They were aslo bought by France, (Spanish Pattern, for the 1870 Franco-Prussian War, +/- 33,000), and also by Turkey, Japan, and the Netherlands.

You might want to look for a copy of, “Peabody Firearms: A Detailed Account of The Peabody Side-Hammer and Peabody-Martini Rifles and Carbines, and The Breechloading Musket Conversions Made on The Patents of Henry O. Peabody”, by Edward Hull. I cannot find my copy, so I am unsure of what it says about cartridges…

Again, my apologies for rambling.

Just want to point out that in your list there are 2 times the caliber 11,43x41R which we should named carbine in difference of the rifle cartridge the 11,43x59R.
I believe thatthe 14,66x35R, the 15,5x35R and the .58 serbian peabody are in fact the same cartridge despite the caliber difference.
You could also add the 11,4x40R romanian peabody carbine cartridge.

Wow Badgerjack, thanks for the in depth reply! It is really hard to get information about these old cartridges from back in the day when cartridge design was (literally) a wild west of innovation. It looks like I’m going to have to do a lot more research to get all the information for the different Peabody cartridges and dates. I’ll look for the book you mentioned.

Thanks Laurent, it gets very challenging when the same cartridge is referred to with different dimensions.

You are welcome!
And here is everything else I was able to find… hope this helps.

.40-70 Peabody “What Cheer”, proprietary
.40-90 Peabody “What Cheer”, proprietary
.44-60 Peabody “Creedmore”, proprietary
.44-90 Peabody “Creedmore”, proprietary
.44-90 Peabody “What Cheer”, aka .44-100 Peabody, proprietary
.44-95 Peabody “What Cheer”, proprietary
.46 Peabody, aka .50 Peabody, proprietary
9.5 Turkish Peabody, aka 9.5x60R Mauser/Turkish Mauser
11.43x41 Peabody-Martini, proprietary [for Turkish Martini]
11.43x49R Romanian Peabody, proprietary [Peabody M67, ca: 1868]
14.66x35R Peabody 1870, aka 14.66 Serbian Peabody, proprietary

Laurent, I have no listing that includes either the 15.5x35R or .58 Serbian.
The information I have indicates the 14.66x35R Peabody/Serbian Peabody did not have any other size or name designation.

Thanks BadgerJack. Very useful.

Basing on “” and the “ECDV” they used 15,5 mm greene, 15x35R serbian peabody, and 14,66x35R for the same cartridge. My apologies it seem that the .58 serbian is in fact a snider cartridge made with a one piece brass case.

I just dug these out of another hard drive [yea, too many hard drives, not enough cross referencing!] on the 10.4x42 Peabody Rimfire cartridge and bullet…
