I have no idea why I never posted my conversions in this thread? I plead the fifth...or insanity, which ever applies.
First, my Goon Walker with .45C Howell conversion cylinder shown...
And next, my Pietta 1858 'Sheriff' conversion with Howell .45C cylinder
In fact, I like the Sheriff conversion so much I've decided to leave it as converted.
I am loading my own BPCR with 250gr lead bullets in front of 35gr 3F powder.
