One more suggestion,
Double rifles are meant to be shot standing up.

Are you doing your shooting off sandbags and sitting?

Just for grins and if your range allows, try shooting
the gun while standing, either a tall bench, crossed sticks,
single shooting stick, etc, you get the picture.

I do believe your elevation concern will come better in focus.

Perhaps, possibly, maybe, we shall see smile
