my monies on you, there is always a way. im sure ill get a homeless joe type response from the experts for even thinking of this fix.how about making plugs that match the inner and outside contours of the barrels and have them welded in and struck to the outside contours of the barrels then have the full length 16 guage inserts welded in. then either have the barrels browned or have them finished with the damascus pattern and faux damascus in the repaired area. i can hardly wait for the pros and cons on this one.
