Rubberhead,
Your statement that the over barrel shoots 3.5-4.0" high, regardless of whether the 150 or 180 grain load is used gives me a hint. When I said you need to shoot the second shot as quickly as you can get back on target, it was because with the bottom barrel warm, if you shoot the cold upper barrel, it will shoot high( when the bottom barrel gets longer, it pushes the other one up). In fact, when I do this, I shoot on two targets( next to each other), because there is no time to locate the first shot before firing the second one. After shooting I transfer the holes from one target to the other. Try that and see how it works.
Mike
