H4831 is one of those powders that you probably can't get too much of in a 270 win case. The maximum SAMMI pressure is 65,000 psi. Hogdon states in their data that 60 grains will create 59,000 psi. It is definitely a compressed charge as it is basically all you can fit in a case without deformation. Lee manual says 60 grains will get to 63,000 psi.
I have found in 270 win and 260 rem that H4831 likes to be compressed. A drop tube is your friend when loading charges like this. In any case you probably can't get enough H4831 in a 270win case to go over 65kpsi with a 130 grain bullet.
If you don't like compressed charges that's fine. There's plenty of powder that work in the 270win.
Good luck and shoot straight y'all
