I'm attempting to load some 130gr seirra in 270 around 3000fps. I I have some factory loaded by Federal that shoot great and that was the fps. I loaded with H4831SC at the same length of the factory round. Went 56.6, 56.8, 57, 57.2, 57,4. Should have hit the 3000 mark in that area. Didn't really have anything worth taking a look at. Was curious how much difference the IMR4831 would be?
