I used H870 with 175 grain Partitions, 175 grain Grand Slams, and 175 grain Trophy Bonded Bear Claws in my 7mm RM. The loads all delivered game for me.
I lean toward Partitions, though I've had considerable success with both AccuBonds and E-Tips. I like these three, and use each of them. They give me a warm, fuzzy feeling when I hunt.:sneaky:
Shot from a 325 WSM; MV ~2500 fps. Game distance from 170 to 220 yards. I eventually switched to 200 grain PT in that rifle in order to get higher velocities of ~2750 fps. This load worked as well as the previous load. I sold the rifle and switched to an 8X68 S, for which I'm still...
I can attest that 130 grain pills will take moose and elk (and a variety of smaller game) quite handily at the velocity you are reporting in your 270 WSM. I use the 130 grain E-tip, however. But I sure wouldn't hesitate to use the 130 grain Partition.
