I shot my .58cal. yesterday and the day before. Don't know if it's because the Colerain is new, but .570" ball with .015" Ox Yoke lubed patch takes a short starter and have to hit it with hand to get started. Tight all the way down. As much as I want to push on a wood rod. I used some .010" or maybe even less...lubed patches and they go down fairly snug and can thumb start..hard but can do it.
However..the barrel is full of lead and one hard long time getting it all out. Not worth the effort..so I'm going to go to a smaller ball .562" and see if I can't get them to shoot with .018" pillow ticking and stop some of the leading.
I guess I will order a .062" mold along with the balls. I don't see any other choice, but to go to smaller ball so I can use thicker patch to stop leading.
