The two powders are almost always within 1 grain of max load from each other in standard rounds like your 270.
Well, I beg to differ. My book says 130gr bullet 270....H4831, max load 60gr. IMR4831, 58gr. Two grains is a bit much for me....'06 is the same deviation. I would never mix and match IMR and Hodgdon. regards, Rick.
