Here is the data I have:

Sierra 3rd edition, 130gr. bullet, 26 inch barrel:

IMR-4350, starting load 48.4gr. velocity ~2,700fps

IMR-4350, MAX load 54.9gr. velocity ~3,100fps

Speer #12 manual, 130gr. bullet, 22 inch barrel:

H4350, starting load 52gr. velocity ~2,733ps

H4350, MAX load 56gr. velocity ~2,949fps

IMR-4350, starting load 51gr. velocity ~2,873fps

IMR-4350, MAX load 55gr. velocity ~2,907

Nosler 5th edition, 130gr. bullet, 24" barrel

IMR-4350, starting load 51gr. velocity ~2,828fps

IMR-4350, MAX load 55gr. velocity ~3,078fps

Hornady fourth edition, 130gr. bullet, 24" barrel

IMR-4350, starting load 50.6gr. velocity ~2,700fps

IMR-4350, MAX load 54.8gr. velocity ~3,000fps

H-4350, starting load 50.7gr. velocity 2,700fps

H-4350, MAX load 56.3gr. velocity ~3,000fps

Hodgdon #26, 24" barrel, Hornady 130gr. bullet

H-4350, starting load 51gr. velocity ~2,865fps

H-4350, MAX load 54.3gr. velocity ~3,012fps

Hodgdon #26, 24" barrel, Nosler 130gr partition

IMR-4350, MAX load only listed, 55gr. velocity ~3,075

Note that in many cases the velocities are rounded to the nearest 100fps. I would take from the data that a safe starting load in the .270 for a 130gr. bullet would be around 50gr. of either IMR or Hodgdon 4350, and I would not exceed 55gr. without specific data from the manufacturer. A chronograph would be helpful if you have one. But that should get you started.

Good luck.
