My 1860 Colt repro and, except for my Second Generation and Third Generation Colts that I have owned and shot, its probably the most accurate handgun I've ever owned.
And like Old Colonel said its a "Labor of love" cleaning it.
Ten shots at 25 yards using 25 grains of GOEx FFFg, a 454 round ball and one Ox Yoke wad with some goo under the ball.
I tried to refinish the grips on it but couldn't get all of the stain out of the wood and they didn't turn out the way I would have liked them. So I shipped it off and had this guy put some Elk grips on. I should have let the grips soak in acetone for a longer period of time.
This guy does excellent work,
