Hey guys has anyone taken the Uberti/Colt 1872 OT in .44 Special and made a conversion cylinder for .44-40?

Reason for me is I recently picked up a nice Winchester 1892 that was made in 1895 and chambered in 44.40. Shoots really well if you load a .430 bullet and wanted a companion SA revolver
for it. Looking at what I have in my collection is a Ruger Flat Top .44 Special which I can get a new cylinder made for it or my 1872 OT in 44 Special. I like the look of the OT as it closer to looking the period.  I do have a 38 Special cylinder for it which could be "possibly" chambered for 44-40. Looking at the measurments  the case dia. of a 44-40 is about .010 larger at base than a .44 Special which should still leave enough cylinder wall for strength of standard 44-40 loads. The case head diameter is about .010 larger than the 44-40 and I have a good .030 of room before the case head would stick out beyond the cylinder O.D.  Case head thickness is same so no issue there.  Cartridge OAL for 44.40 is 1.580 as I load them and the 44 Special cylinder OAL is 1.608 so if I use a tight crimp hopefully bullet jump would not lock it up with typical Cowboy Action loads.

What do you think?

The Battle of Ciudad Juárez in 1911 is our theme for this Expansion Era Muster. There will be three skirmish runs and a precision rifle match with the precision pistol included in one of the skirmish runs.

The round count for the skirmish runs will be 27 rifle and 22 pistol. We will also will need 10 for the precision rifle match.

Registration starts at 9:00 AM with Safety Brief and first skirmish run beginning at 9:30 AM.

Cost is $10.

The able woodcrafter didn't specifically mention it, but in your direction, I would think you'd powder coat before sizing.  That may also help with some of the undersize bullets.

Check out NCOWS and Barracks.   There is the NCOWS posse in Valparaiso and they are a great group!  Due south in Kansas (Garnett) is the NCOWS KVC posse.  I am involved with that one.   We will host the NCOWS National shoot in June 2024 at Parker Kansas.   And Sargent has the Grand Muster.   Seriously great times at all these locations.   Shooting and ranges are great, the people even better. 

Looks great. What top coat did you use to rub in?

Thank you. I used Tan-Kote hand rubbed with an old Tee Shirt.
