Great discussion. Lately I've had trouble getting proper scope/rifle position set for me. I don't know what has changed, eyes for sure, but seems like the scope is too short even purchased set back rings but still having trouble. Don't know if the damn neck surgery has changed my head position??? This has happened on three rifles lately. Head position is too far forward to get full scope picture. This with the old Redfields of yesteryear that worked fine for a younger HM!
