I shoot the same exact load except that I use 17.0-700x and 1oz of Mag 8's for trap upto the 20yd line and then go to 1-1/8th of 8's over 20yds. I as well shoot AA class and only change chokes from 16 to 27yd. When it is real hot out I will shoot 9's in place of 8's up to the 20 yd line. Great load!!!!! I even load the same thing out of Fed. Paper hulls also.
