You can practice the needed leads with 1200 fps 7 1/2s target loads on a skeet range on stations 3,4&5 by backing up the appropriate distance. Check the ballistics for elapsed time of flight to a given distance for your steel load and then for the target load back up from station 3,4 or 5 so the ET is the same as your steel load at a chosen hunting distance. Our gun club used to have skeet machines on a 100' construction elevator that we could raise the machines from the ground to 100'. The tower machine range was very popular with all of our conscientious wingshots but we were restricted to 7 1/2s or smaller shot so we adjusted.
