Look at the Hogdon's reloading web site. They have posted or reposted reloads originally tested by Sisley in RST/ Cheddit hulls some time ago in Skeet Shooting magazine. Most use the dr-16 rather than the BP wad, for 3/4 and 7/8 loads. Universal, International, and 20-28 powders have replaced PB and 7625, now discontinued. good shooting,
