Varget will work it seems to be a pretty broad application powder suitable for small cases in small caliber in to heavy for cartridge type like 70 gr 223 and on up to straight and nearly strait cases like 30-30 and 45-70 . It's not optimum in them all but it's pretty good looking at data .

For 30-30 , 06' , 280 Rem , 7×57 , and 308 I use IMR 4350 although H4350 would probably yield equally good results . My Dad liked H4831 in his 25-06' , I am pleased with H1000 in a 264 WM and will try it eventually in Dad's 25-06' .
