Those two components are the peanut better and jelly of the .270 win., they just go together so well. I like 56.0 grs. of IMR-4350 with a 130 grainer for an accurate 3150 fps load.
I don't think it's possible to over charge with IMR-4350 in a 270 win case with a 130 gr. projectile. In other words, I have filled them to the top of the neck with IMR-4350 without any worries. I'm not suggesting anyone ever do that without having first worked up your loads, but I have.
Killed a lot of game with that combination.
