Jim, I did, As soon as you first posted I put answer to your questions in my original post.
I missed seeing the answer, sorry. It says the problem is in the gun. As both barrels are shooting low, bending the barrels up would be the easiest remedy. Removing metal from inside the muzzles will move the patterns in that direction BUT will make the patterns a bit larger. If you're happy with the chokes as they are, bending the barrels seems the way to go. Old man Purbaugh is said to have used a drawer in his shop, to bend barrels. He would put the barrel(s) in the drawer and lean on it until it bent. I like the idea of a press, better. Best wishes with it.
