I think I'll just go ahead and buy a jug of H4350 ,I've been looking at the data on it and it looks like it's also a good powder for the 30-06,and the 7mm-08,even though I can't complain about my current load with IMR4064 for the 7-08..I had intended on using the 4064 for the 30-06,because I already have it on hand,but if I buy the H4350 I'll experiment with both..thanks for all the valuble advice everyone.
