Regarding .270 velocity for 150s, I don't have the reloading experience to make an informed comment. All I know is what I have read and my thinking was that if Winchester originally designed 130s with a velocity of 3,140 and later reduced the velocity to 3,060 fps, a target velocity of 3,000 fps for 150s would probably be ok (but I could definitely be mistaken). I can certainly see how 3,000 fps for 150s would increase pressures, though.
