Enjoyed the recent post on arbor shimming. My question is how are you setting the b/c gap if the arbor is now bottomed out in the barrel? You must be removing metal from somewhere(barrel lug?) to close the gap to .002 as 45 Dragoon suggests. Of course, I assume this is done prior to any adjustments to the arbor/barrel relationship.
I have always gone with the usual suggestion to keep the b/c gap at about.008-.010 for these blackpowder guns and when I have previously adjusted the arbor on a bunch of Ubertis' they pretty much have fallen within this range. But recent discourse from 45 Dragoon makes me think a tight b/c gap can work. By the way, all I shoot is blackpowder.
