I'm looking into powders for an AR for general range time. On my short list is H335. 1 pound bottle $42.95, or $171.80 for 4 pounds. Or a 4 pound jug for $148, $37 a pound saving $23.80. I won't be using it too quickly. Am I better off paying the extra $5.95 a pound to have singles or does it keep ok once opened so save the money? Almost certain I know but confirmation is always nice. Thanks.
