Regulation is high but shoots low. Regulation left and shoots left. As Dale Tate once told me...bend the barrels as needed. Sounds simple...but it works! Funniest thing in the world to see a grown man sitting on a set of double barrels during a shoot to change the POI. Of course, he was not doing it from a lack of knowledge. He had Purdey's of London training!
Pitch is greater on gun #2. POI is different. Sounds like the restock is your culprit. Comb thickness the same? Send the gun to a competent stock bender to have your gun altered to bring both guns into same standards of your choice. There are many here to choose from. Call, Ask, Decide.
