B&P Legend size 9 vs 80yd battue

Using a size 9 1/2 (9 UK) B&P Legend on an 80 yard battue target at Garlands near Tamworth, Staffs. As stated in the video, I would not use this size cartridge in a competition scenario. I would probably choose a 7 1/2 for this target. By using a cartridge containing larger pellets, the shot would carry more energy downrange and therefore, should need less pellets to break the clay and be less affected by weather conditions.
