I have used (and am still using) Hercules 2400 (yes, Hercules not Alliant) powder in my 22 Hornet with good results for eons. My loads were developed in the late 1960's based on the loading data then published, and I found the best results using 9.5 gr. with a 40 gr. bullet. My supply of Hercules 2400 is about to run out, so will be switching to using Alliant 2400. From all info I've found online, the consensus is that the Hercules and Alliant 2400 powders are essentially the same with only the typical lot-to-lot variations one would expect to find with all powders. However, newer data sources, which would be based on Alliant 2400, list load levels considerably lower that what the older data sources listed that were based on Hercules 2400. So, this leads me to wonder if the older and newer powders by the 2400 name are indeed the same? Or, is the new load data based on lawyer CYA influence? This is not specific to 2400 as I've noticed all load data in the newer data sources suggest lower loading levels than older data sources provided for the same powders.
