I use H414 exclusively for the 30-06 and have been doing so for many years. Looks like I am not alone. I have never used magnum primers, always WW large rifle primers. I have tried many powders and IMHO H414 provides superior accuracy.
There is only one exception when I do not use this powder and that would be when reloading for the M1 Garand. For the Garand I use 4895.
