For hunting with my FP, I shoot 165gr Speer Hot-Cor's. They have killed every animal from a 6X6 elk to rockchucks without an issue.
For my bench work, I am also a 175SMK guy. However I am exclusively a Win 748 man. I can launch the 175's past 2600fps with less pressure, than when I use Varget; I also get more rounds down-range, with less heat when using 748.

My accuracy load is 43.5 gr 748, with that load I can interchange LC, or commercial mixed headstamp brass without pressures.
