Believe that's correct Chas.
The longest shot I have any extensive experience with is the old trap 'porch shoot'. We used to shoot from a point in line with the clubhouse porch benches, directly behind trap #4.
It approximates 40 yard trap. Distance to target peak, which is the only place they seem to break, would be 70 yards +/-.
Time of flight is more than 2/10's of a second, and the target moves many feet. It's a tough shot, but during our events I'd estimate the 27 yard men averaged half or a little better. I shot 9 for 10 once and won enough to keep me in shells and targets for the rest of the afternoon! Great memories of that place.
The trick was to note against the background the horizontal line where the targets peaked. Hold on that line, and when you see a flash of orange, guess the angle vector and shoot along the peak line where you think it's going to be.
Normal trap technique does not work.
Some guys used field loads of 6's, I had the most success with factory new Federal Champions in 7 1/2.
It's a game of chance at that point, but luck favors the better shooters.
