A couple other thoughts.
1. Several years ago Tom Roster did a lot of work with steel shot and chokes that was I guess proprietary that I used to see in state game and fish agency waterfowl reg publications. Apparently he compiled data from thousands of shots.

2. The woman who won the Olympic gold medal for trap, which is international trap (targets at around 60 mph compared to around 40 mph for American trap), went 125 for 125 in the two days of qualifying for the finals. IIRC her closest competitor missed at least 3 or 4 (perhaps 5) targets in the qualifying round. I imagine a lot of work went into finding the right combination of choke and load components that she used.
