BB, as you know, many of the ADI powders are imported to the US and relabeled as Hodgdon powders. This has been going o n for decades. The powders translate from ADI to Hodgdon as follows:
AS30N=Clays
AP50N = (No Hodgdon)
AS50N = International Clays
AP70N = Universal Clays
AP100 = (No Hodgdon)
AR2205 = H4227
AR2207 = H4198
AR2219 = H322
Bench Mark1 = (No Hodgdon)
Bench Mark2 = BenchMark
AR2206 = (No Hodgdon)
AR2206H = H4895
AR2208 = Varget
AR2209 = H4350
AR2213 = (Discontinued)
AR2213SC = H4831
AR2217 = H1000
AR2225 = Retumbo
AR2218 = H50BMG
So if you have data for either name, it is interchangeable, with the understanding as you state above, that you start at the start charges and work up carefully. Nosler, Barnes, and others now post their data online, so if you have a need for specific data, perhaps this will broaden your horizon of possibilities.
