I coned my recent acquisition, a .54 Woodsrunner, a couple weeks ago. I loaded it up for the deer season here and was really surprised that I could load the .530, and a .15 patch, which for my bore is a tight fit, and was able to do it with just a thumb press and then using the ramrod to shove it down. Easy as could be. Prior to coning, I used a ball starter and really had to whomp it to get that combination started. Since I have not had accuracy problems with the other three guns I coned, I don't think I will have any with this.
Joe Woods tools, by the way. Two .54 and two .45 done. Another .54 is a conical bullet only, so no coning done on it.
The Doc is out now.
