After I got my 270 back in the late 70's, I read an O'Connor article where he gave 60 grains of H4831 as his load for the 270 with 130 grain bullets. That's where I started out, and what I still use today.
That load, with Remington brass and a Federal 210 primer, gives me 3100 FPS out of the 22" barrel of my Ottmar stocked .270, as measured by my LabRadar.
Happily it is wonderfully accurate as well.
