I have a shooting grade colt 2nd gen 1st m dragoon.cap n ball.
chamber mouths are .451,but get this..
bore dia. is .442, groove diameter is .468!
deep ass rifling.
Now the question what to do?
I am thinking reaming the cylinder throats to take a .480 ball, reaming .473/.475"
or, take a .457 mold and put a 15/32" ball end mill cutter into each half,thus making a .469 round ball mold,and reaming the cylinder throats to .466"
or leave it alone,which I`m not going to do:Fire:
certainly interesting project.
