Dixie Rebel,

I have probably shot thousands of rounds with both IMR4350 and H4350 in various .30-06s, especially with various 165-180 grain bullets. They both work great--have yet to encounter the same combination of consistent high velocity combined with accuracy that I have with Hunter, also in far more than one rifle. But whatever....
