I know it's confusing BPS but Semi is correct. With a free moving barrel the heavier bullet will hit higher at ranges before drop or BC is an issue such as 25-50 yards with a connie or a RB. It's not that the shooter causes the barrel to rise. It's the natural movement of recoil itself that causes barrel rise. Physics can certainly cause headaches in people with a lot of common sense because sometimes it just don't make sense!
