Thanks everyone for the suggestions. Keep them coming. Looks like h4831sc has a few fans.
True. But, I would not use a suboptimal powder for that reason alone. Opening a new can from a new lot is not like starting over completely.
Unless you're using it up quickly, smaller cans stay fresh longer (IMHO) because you only need to open them as you need them.
You can easily check the lot numbers on the one pound cans. If the store has several one pound cans, the lot numbers will most likely match.
That's what I do after testing a particular lot; and to ensure my dope doesn't suddenly change; and to help avoid limiting myself too much on my powder choices.
That said, you may be able to get good results with one or two powders for your rifles.
