Cool! Tell us more - is it a rebore and open the chambers, or more involved? What size is everything?

+1 on the above! Inquiring minds want to know!

+ 1 ^ ^ ^ ^ ^ Tell us more please and don't leave us hanging . . . :-) what is the bore size and what is the ball size you are using? If it is like Colt's other pistols - I'm guessing the barrel is bored .400 and then rifled? Is this a "one of a kind" or is Taylor going to stock them? Thanks!

Taylor Machine in Puyallup, WA is John Taylor. A clever mechanic and gunsmith.
Taylor & Co. who imports the cowboy guns is a different outfit, in Winchester, VA.

Mr. Taylor was going to rebore the barrel but needed to use a sleeve instead (securing the barrel in his rifling machine was a problem).
It's got 38-40 rifling and .403 chambers. Chamber mouths are nicely transitioned to swage balls in and avoid cutting rings. The balls are from a Lyman .410 mold.
This makes for a nice shooting revolver. Eh, do I need a rifle to .41 ball?
Merry Christmas!

This was one of those fun projects that was different so it got me a little interested. Breach plugs on a SXS 4 bore are in the works now. For a barrel to work in my rifling machine it needs to be 20" long, a little longer for the reaming machine. Sometimes I can slide a tube over the barrel to make it longer but on the Colt stile I could not figure a way to hold it. Several years back an old timer sent me a video of converting an 1851 to 22 LR, now to find one that is cheep to try it on.

very easy to doo. The MORE FUN option is to recreate the old factory 22 lr conversion for standard solid frame revolvers.
Already done a 22 LR conversion. I think a 7 or 8 shot cylinder might be fun in a 22 LR. Will need to do some thinking on it but first I need to finish a bunch of other projects.

Chamber mouths are nicely transitioned to swage balls in and avoid cutting rings.
Long time usage suggests that using a RB that's slightly larger than the chamber mouth is best, since the shaving of a thin lead ring guarantee's that the front of the chamber will be sealed - so may I ask why one would want to avoid cutting rings off the ball during seating ? ?

His chambers are chamfered. This way the .410" ball going into the .403" chamber still creates a wide driving band as would in a typical situation, but doesn't leave that ring of lead which is kind of a waste but also leaves something that needs to be removed. I dislike how the rings from my projectiles stick to stuff because of the Gatofeo's lube.

It's running a short oversized boolit into a sizer die.
The lead flows in instead of shearing off is all.
