What used to be AA-3100 (before Western Powders bought the old Accurate Arms Co.) is Lovex SO71 which is apparently available in the US.

Western stopped buying Czech manufactured powders after the takeover, so there may have been a North American made version between that time and Western dropping the grade. I believe that Accurate brand extruded grades are manufactured by the General Dynamics Valleyfield plant in Quebec Province, Canada - the same people who make most IMR powders. (Ball grades, both Accurate and Ramshot, are made in Belgium.) I've no knowledge though as to whether there was a Canadian made version of 3100.
