It's an academic question.
Ever seen a Trap shooter pry his barrels up using the gap between a trucks bumper and the tailgate?

I want to know if the mostly unseen rib elevated the POI or some interesting barrel work.
The stock looks pretty flat.

When I said 95-5 patterns, I meant the % of the pellets hitting above poa. And 5% is generous.

Not everything shot at is rising. Chukars fly down the mountainsaide, so do Francolin. And ducks, well, they are inclined to "drop right in".

Out there doing it best I can.
