Something I learned by accident, after years of not being worth a hoot at shotgunning: I did the IPSC thing for three years before moving out to the desert. The first dove season there, I found that doves were easy: "Front sight, press."
Granted, the old Model 12 fits me. With proper hold, I look right down the plane of the top of the ribbed barrel, barely seeing the front bead.
If you can see the top of the barrel, you'll shoot high. If you have to raise your head slightly to see the front bead, you'll shoot low.
