I use H 414 exclusively in the .30-06 nowadays. I have used IMR 4350, 4064 and 4895 in the past with good results. But the 414 is a spherical powder that meters perfectly through powder measures, and shoots very accurately in my rifles. 414 is basically a spherical version of 4350, i.e., they burn at about the same rate.
For 454 Casull, .44 Magnum, and .357 Magnum, I've had my best results with H110. Currently, I use H 110 exclusively in these calibres.
If you think a mighty military force is expensive, wait 'til you see what a weak one costs.
