Sounds like your only problem will be figuring out which guns to use!

Thanks! I have a small machine shop but the cost of the roughing and finish chamber reamer is over 300 bucks. Haven't a shop yet that can do the job using my 38 Special cylinder.

It will give you the general guidelines.   You can use the typical cowboy arms, and clothing and shoot in the civilian class.   If you have those handy, it may be a good starting point before delving into military arms.   if you have 19th century military equipment, this is the place for it.   I picked up a trapdoor after my first one.   the bug will bite you hard.

River City, historicly, I have not asked for donations for door prizes,  so I will not be taking them this year. However it is something that stands to be discussed  with my staff for next year. Thanks anyway.w

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?
