[QUOTE="CogburnR, post: 453778, member: 29174"] Generally with a 270 if you are having accuracy problems go to IMR4350 and see if your problem goes away. It would take a case full of 4831 to get pressure with a 90g bullet. In my rifles 4831 gives good velocity with reasonable accuracy(the hot loads shoot okay), 4350 is more accurate but generally not at max pressure so they are slower. I used 4831 in max hunting loads and 4350 to shoot paper tigers. Now there are powders like Magpro that will add 150fps onto 4831 loads. [/QUOTE]
