I've found that Reloder 7 is a great cast boolit powder........at least in the .250 Savage. It meters very well thru my Dillon 450 powder measure. The other day I went to a local Coeur d'Alene, Id. sporting goods store, and while they had every other "flavor" of Alliant powder, they were out of Rel 7, and did not know if it was going to be available again. I contacted Alliant and they assured me that it is still being manufactured and should be available.
