Jayco - I don't have any real argument about that. IMO the 150s aren't much heavy for caliber in the 270.
JOC used the 150s quite a bit, 58-59 grs. of Surplus 4831 and vel. 2900-3000 depending upon rifle & barrel. He like the 150s for heavier game IIRC and I remember that he did use a 130 on Moose at least once.
The OP simply asked about the chronod vel. of factory Federals w/150 partitions. He didn't state his intended purpose. I'd predict that no one could tell the difference between 130 and 150 grain Partitions, at least most of the time.
