Your barrel is rifled for a round ball, so this limits your choices of bullets. They say I could 'ring' their $300+ cylinder. Taylor's is adamant about not using fillers or spacers in the 45 Colt brass. With 45 Colt brass, you are going to get flyers, from lousy ignition. Your Taylor's converter should accept the 0.519' rims of Star Line 45 S & W Schofield cases. Using 45 S & W Schofield brass solves this problem. RNFP's by Desperado Cowboy Bullets in Dayton, Washington, also have noses a little long, but you can mash a F.P. Your cylinder is a bit short, so Keith SWC's won't fit, unless you seat them down and crimp over their front bearing band. So you need to go for the bottom rung, published loads in the manuals. The weak point isn't in their cylinder, its in your revolver, itself. So shooting strings of Black Powder is out. I asked him to fit it as tightly as possible, which he did. Actually, I think he simply made a new backing plate, and put mine back into stock. 'Tom' fitted it, by grinding away a bit on the backing plate. So I sent it back to Taylor's and their G.S. I purchased the Pietta version, but it was too long. I use a Taylor's six shot SS converter cylinder in an old Armi San Paolo replica.
