Thanks for that Daryl, I will look out for the problems you describe. I just finished a problem cycle with my muzzleloader I am perhaps inclined to diagnose the change while the stockmaker had it as due to changing wood relationships so I wont assume.

My first thought about the crossing fire was similar to yours, and I bought and adapted a crimp die to make sure the loads were giving their all, and upped the charge to a thoughtful maximum as well; there was no difference in POI. And the crossing is very marked, its right barrel shoots about 6" left at 15 yards and the left about 3" high and 1" right. I can no longer hope that its just a load issue.
