.44-40 sizing troubles... rifle vs. revolver ?

[Ya Big Tree]

It is the cylinder that is the problem.  I can't even seat the cartridge if I use .429 bullets.

I've had the Smoke Wagons since 2009. Jim Finch (Longhunter) did the tuning on them.

I have no doubt that they are made for a .427 bullet as you say, but if the bore is .429/.430 you can ream the throat on the cylinder allowing you to shoot .429 diameter. Both of my Vaqueros had .427 cylinder throats and .4295 bores.
A .4305 reamer took care of the problem. Now I run .429 diameter bullets in two rifles and three Vaqueros.

Well that might be so but the Uberti single action revolver I bought in 2019 from Cimarron - it's a 44 WCF - has a .427" barrel and a .427" cylinder. The internet swore about the barrel being .430" diameter. The internet was wrong.

Ruger has always used .429 barrels for their .44-40 revolvers.  I haven't slugged my bores, but Taylor's reports that Smoke Wagons have a bore diameter of 0.4125". Which is tight.

SAAMI lists the bore diameter for .44-40 Rifle should be 0.4225" (+0.002") and groove of 0.4285" (+0.002").
SAAMI for .44 Magnum rifle is 0.424"/0.431" (+.004") and for .44 Special (& Magnum) pistol it is 0.417"/0.429" (+.004")

Could that 0.4125" Smoke Wagon bore diameter be a mistake, on either your part or Taylor's?  Because Uberti specs it at 0.4215"  (Which is not to say that Uberti always follows their specs.)  see Uberti's specs: https://www.cimarron-firearms.com/bore-groove-twist

Yep, typo on my part.  It is 0.4215" on the Taylor's website.
