Can you suggest a correct ball diameter?
I have my old (45 years old) Italian, brass frame, open top, Colt copy, 36 cal cap & ball revolver and want to get it going again. I have never cast for it and so need a mold of proper size.
I have a set of pin gauges, so I checked the cylinder mouths. All excepted 0.356" and two 0.357". I have not sluged the barrel but I will at some point.
My Ruger Old Army cylinders measure 0.451" and it is stated to use 0.457" balls, and that is what I do. They work well.
Using this as a guide, I could use a 0.365" ball in the 36 Colt. But I think people normally use 0.375", and I bought 0.375" in the past. I think?
I wonder what might be better?
