Hi Bill, great question, the rifle has always been quite nose heavy and still is even after removing all the extra forend wood. I suppose it did move back slightly and the balance seems to be in the exact middle of the entry pipe right now. I hung some lead weights off the back of the butt plate and 4 oz would bring it to neutral where I would normally hold with my support hand. I suppose it would take 5 oz once inletted into the butt stock or leave at 4oz for slightly nose heavy.
