50 cal Peabody

Greetings
I nearly had to gasp... but then that is only the third one I have seen up for sale. Thank you for posting it. It has been awhile since I did that search.
I like the Peabody. Would be nice to have the 45-70 down here to shoot a lot.. but that is beyond the parameters of this nation.

Thanks for the sending 'bout the Peabody .50
The carbine listed above on gunbroker is a .50 rimfire.  Now there's a couple of ways today to use a .50 rimfire Peabody:
1.  find a cache of .56-50 rimfire Spencer rimfire ammunition, and hopefully it'd still fire after all these years!
.56-50 Spencer ammo?  Yes, the case is a bit shorter than a .50 Peabody rimfire round but works just fine. In the late 1800's Canada used .577 Snyder's; .56-50 Spencer's; and Peabody's in .50 rimfire. Seeing as how the .56-50 Spencer worked in the Peabody's, that's what they stocked for use in both the Spencer and Peabody, for logistical purposes. Of note, anyone obtaining a Peabody .50 rimfire should be sure the chamber doesn't have a build-up of lead in the chamber, from there having been used .56-50 Spencer ammo.
2.  replace the .50 rimfire breech block with a centerfire breech block and either put a spacing washer (to offest the rimfire hammer slightly away from the receiver, in order for the hammer nose to clear properly), or order a centerfire hammer from Providence Tool Co. in Wisconsin.   Then order .56-50 brass from Starline and head out to the range n' see how it performs.
The gentleman here did this with his .50 rimfire Peabody and gives the basic details: www.gunbroker.com/Auction/ViewItem.aspx?Item=538015151

Several years ago I acquired a Peabody carbine that had been converted by a North Carolina gunsmith. obtained from his estate.  He had converted and refinished a Peabody .50 rimfire, 1 of 350 carbines shipped to South Carolina in 1877, to centerfire and then opened up the chamber to .50 1 3/4" (aka: .50-70 Gov't).  I'd been on the scout back then for a suitable Peabody .50 rimfire carbine for such a conversion project. His work saved me a lot of work.  Will post some other information about Peabody irons in a week or so.  Yes, I do like n' enjoy Peabody's.

In a pinch you can use 30-40 brass.
