I think that’s not the tool for the job. I can’t figure out how your position merry it, then expand it, then retract it. Nor can I cipher how to not end up with square edges in the area being worked.l.

That reamer is for bronze bushings. It will not cut steel CLEANLY. I made jug choking tool out of a piece of 3/8 key stock, a file and a piece of 3/8 ram rod.

I have used a Lewis lead remover with sandpaper on it and spun up with an electric drill.

I jugged a .44 calibre smoothbore using a brake cylinder hone. After the stones wore out, I contact cemented 320grit emery onto the steel pads.
Worked perfectly - wonderful patters. Broke 10 straight shooting against 12 bore SxS's and a 10 bore as well. Won the match, shot
from the 16 yard position. I used 3/4oz. shot and 45gr. 3F, IIRC.
That gun also shot patched round balls quite well.

Is geometry critical?
