It seems to me that if you want 3100fps with a 140 gr bullet in your 270, you are not going to get it, unless you go to a 270 Weatherby or Maybe the 270WSM, I never gotten a 140 gr bullet to shoot very well in any of the 270's I owned in the pass, never found it to be lacking, since I killed ever thing I shot with 130 gr bullets, I don't know if its worth going thru the expense for that 100 to 150 fps difference or not, that is your call on that one. You could just work up a good load, and call it 3100 fps in your head and leave it at that, the game will never know and its doubt full that you would be able to tell under field shooting conditions. You can just put so much fuel into a 30-06 size case and that it, more fuel is going to require a bigger case for very little real gain- that is just how it is, What voodoo federal did with those "High Energy" loads could be a subject to a whole book ! They were great if they shot well in your rifle!
