It looks like 67 grains is the magic load for my 300wsm. 150 grain accubonds and 67 grains of RL17 and with 180 accubonds and 67 grains of RL22 . Both these loads group well in my Browning Xbolt. No pressure signs . I do not know the FPS but they are fast enough for my hunting.
Thoughs accubonds shoot as good as any target grade bullet I ever shot.
