My Model 70 in 7mm RM is one of my oldest rifles. It is definitely a shooter. If there wasn't a border between us (and DHS blocking such sales), I'd sure be tempted to pick this up, just because. Looks to be a winner for someone.
Twenty-two inch barrel. I kept all OAL at 2.80 inches to fit magazine. My loads worked quite well on moose, elk, and black bear. I never used the cartridge on grizzly, but I had no doubt it would work quite well if the need were to arise.
I tested RL with Hornady 250 SP, achieving 2565 fps. I also tested W748 with Woodleigh 250 RN to deliver 2524 fps. My hunting loads were built around either 200 grain TSX or 225 grain Nosler PT. Powerhouse loads, all.
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.
