Ballistics products sent me a free data packet on loading short shells. It is copyrighted 2017 and uses a variety of powders, including International, green Dot, Bullseye, titewad, clays,red dot 800x, universal, alliant 20/28, Longshot and unique. I have it saved on the cloud. Gauges are 12, 16 and 28. . I load 12 and 16 short shells and did load 2" using their data. I have two lifetimes' supply of unique. If someone can find a way to publish it, I'll email it to them. PM me your email address.
