I have had my best success using IMR-7828 powder with 160 grain bullets. I am using that powder to load 168 Grain Berger's for target shooting and I also used it to load 160 Barnes TSX for elk hunting. I loaded 60.5 grains in RP case with WLRM primers and according to my Chronograph this produced an average of 2953 ft/sec.
I started working up loads using 160 Accubond bullets using RL-22. I did not get as good a results so I stopped.
