Anyone know if h4350 can be substituded for imr 4350 using the same grain weight as suggested loads in speer-sierra and hornaday manuals??-I'm reloading 8mm-06 and find plenty of loads using imr 4350 but only have h4350 on hand-thanks for any help

H4350 is slightly slower than IMR 4350. I could not find loads for 8mm-06 using either powder.

I just got off the phone with Mike of Hogdon's and he gave an ok to sub H4350 instead of IMR 4350- just start with the starting loads and work up, makes sense as H4350 is just a little slower that the IMR 4350
