You might be able to expand that flange back out with something like a 5/8"-11/16" bolt with a chamfer on it, then re-seat the plug back to the barrel? Since you already filled in the slot for the tool, you would have to wrap some leather around the back end and use something like vice grips to re-seat it.
Looks like you may have problems at the other end as well? Too deep? Too wide? Leaking through the adapter?
Only had 4 vials of powder left. Pressing the 5/8" bolt into the breech plug, and redoing the marriage of the plug to the barrel, did help. The fit isn't perfect, but far less soot got past the rim of the breech plug. As expected there is no change to the leakage at the primer end. Perhaps adding a 0.005" shim or so, behind the firing pin bushing will cure the leak, maybe..
Wow, the point of impact sure changed this morning. Temperature was a way warmer, 36 degree, is that why? In order to fit the plug to the barrel using a little pipe wrench, i had to remove the fore end, and barrel from the breech, is that why? Seems the removal and replacement could have changed the impact. The screw holding the fore end seemed kinda loose when i removed it, and i am sure it is tighter now than it was.
