Funny, I'm one that thinks the 140/150's are the 270's "natural" weights... but I digress.
Just pulled out some data from 1996... I ran an entire box of WW 150 Power Points through my 22" M70 Fwt. Chron'd them all.
Velocity was 2,640-2,702 fps for an average of 2,680 fps for all 20 shots.
Dat's pitiful!
I would expect the Fedral 150 Partition load will be similar...
