I've pattern tested modern Super X 12's against the old "Super Pigeon" formula, which is 3 1/4 DE rather than 3 3/4 and about 100 fps slower. The latter throws better patterns, but the Super-X isn't bad. It clearly outpatterns the very high speed (14-1500 fps) lead loads I've patterned . . . in addition to having milder recoil.
