If I was working up a load in today's environment, I would make up a list of powders that have worked for others and buy 8 lbs of which ever powder I can buy. 8 lbs of a powder that give 1 MOA ,trumps 1 lb of powder that gives 1/2 MOA. At least I could shoot something until powder becomes available again. Figure about a year for things to get back to the new "normal".
