Try putting one of the wrap around padded comb risers that attach with an elastic velcro band on your gun. This will (or should) make you see a good bit of the rib when you mount the gun and your patterns should print slightly high. I never look at the corner or edge of the trap house, but focus 2-3 ft above. Pretend it's a flushing quail or pheasant when you call pull and shoot instinctively. Want to have fun? Have up to a 3 second delay when you call for the bird. Accuriser, I believe, is the name of the attachment.
