Your gun might be fussy as some are. Mine works extremely well with IMR4064. I was very comfortable with that powder, but decided to try another powder and got tighter groups, with RL22. Just goes to show that you should test several powders, but the two you listed are both great powders !
That was the load I used in my first .270. Got it out of my Jack O'Connor book and shot the hell out of everything with it. Used Sierras too, whatever the gas station had on sale or in stock. Its 2 grains over the current max according to the Hodgdons site but nothing broke.
IMR4350 gives a tick more velocity, but it uses a tick more powder to do it.
You picked which 130? A Barnes TSX gets a tick more velocity with the same loads as a non-copper bullet. Longer OAL and much higher pressures to get there though.
