So five years later I have finally made some progress. Went to the range with my new front sight and barrel bending jig after settling on 4 drams of Swiss and a patched 16bore ball. First time I have shot it from a bench. In times past I went to the forest but we have shooting ban in place currently due to the dry conditions. I certainly shoots to the right but not a bad as I remembered.

bending jig

Front sight is bench made, gold bead by Charles Lee.

target used to verify windage, all the shots 3-5 inches to the right were shot before any barrel bending. It did not take much, .025" bend in the middle to bring things right into line.

final shot on a clean target to verify my work

My shoulder was very sore at this point. Nice shooter while standing....kinda sucks from the bench.

and with some new screws, a stock refinish and repair, new bridle, fly and sear spring it only requires barrel browning now.
