PS Mark Wiz, I have not found a moisture problem with the clean shot powder, I got all nervous when they were talking going out of biz during the suit and picked up 3 jugs. Been shooting fine thru almost 2 of them in close to a year. I do store them (as I do with all my powders) in a 20 mm ammo can with desicant packs in a cool,dry dark place in the house. The stuff isnt cheap, dont just throw it in the garage. Pick a place that the temps remain consistant and you should not have a problem.
