Never tried H-4350 cuz I got hooked on IMR-4350 early on, but I'm sure its great... particuarly now that they have the "extreme" line that isn't as temp sensative.

My favored 165 load utilizes RL-19, but those three would seem to me to be the ideals to start with: RL19, IMR- & H-4350s.

RL 19 gives me 2900 fps from a 165 gr SST without signs of pressure at all. With 61 gr in a 23.6" barrel it is over max so look up book starting numbers and work your way up.
