I experiment too much, with too many rifles and cartridges, to have one favorite. Plus, there are so damn many new powders to test, and quite a few turn out to be really good! Right now I have 91 different smokeless powders on hand, and while some are for handguns and shotguns, probably 80% are primarily rifle powders.
Right now the top ones on my list of loads for our various rifles are Varget, TAC, H4895, Big Game, Accurate 5744 and IMR4451. H4350 used to be right up there, but since it became scarce I started using 4451 in the same loads and rifles, and so far it's done as well or better in every one, and even in some I hadn't loaded for before, like the 6XC. But Reloder 23 and 26 are also starting to find their way onto the "short" list....
Based on your rec, I started using IMR 4451, specifically in my 243 RAR. It loves that powder with 95 BT, 100Partitions, and 105 AMAX. Thanks!
