I am about out of the powder that I've been using for several years. I load both 30-30 and 30-06 with it. I want to try a new recipe with the new can of powder. My book is pretty old and the IMR 3031 is the best overall performance in both guns from the 30 year old charts I have. Does anyone have a newer book with some newer powders? I'm looking for one powder that will work well in both calibers. Any ideas? I load 170 and 180 grain flat nose or soft round point bullets. I've been loading 27 grs. of IMR 3031 in the 30-30. I load 45 grs. of IMR 3031 in the 30-06. Both leave plenty of empty room in the case.
