I am sure you are all over this however you seem to be conflating true equivalence with burn rate equivalent. There is a list of ADI powders that are made here for Hodgdon and re-packaged by them - they are exactly the same and can be used 1:1
ADI Powder.......... Hodgdon naming

AS50N.................International
AP70N.................Universal
AR2205...............H4227
AR2207...............H4198

Burning rate equivalent charts like the one at the back of the ADI booklet cannot be used to extrapolate loading information. However they do provide useful information guiding powder choice if you usual favourite powder is not available.
