So all Hodgdon & Win ball powders come from that plant. I don't know the Accurate line well enough, but 2700=414=760; so at least that one too.
Alliant's USA made powders WERE made by ATK in the Militarys Radford Arsenal, since they lost the contact to run the plant; I don't know if BAE will continue that.
Unless it is a "contract" production run, when I say "made by", I mean the non-canister parent.
As an example: SMP 842 is where CFE223 comes from.
