Have shot 165's over H4350 for years but moved up to a 180 NAB for an elk hunt using my M70. Started from scratch on powders. After several rounds of testing, I settled on (surprisingly to me) Re-17. Had some good groups from Re-22 and H4350 at 100, but they fell off at 200 while Re-17 shot MOA (or sub-) at both 100 & 200. IMR4350, Re-19 and Hunter never made it to the second round. When starting this process, I expected it to be either Hunter or H4350. Nice to be done.
Did you use a magnum primer with Hunter powder in the 30/06? Hunter and 180s generally shines as long as a magnum primer is used.
