Bclc&Au talking about 4350 and the .257 Bob got me to review data. 4064 and the .35 Whelen works well. 4831& the .473 '06 family hard to beat. Varget and the .308 family same deal. Experience shows that most us handloaders have at least 2 "backup loads' when we can't get a certain componet (Curse you Alliant for speeding up 2400's burn rate!) I found W760 works decently in .30-30 not as well as W748 but it'll work.
