My 270 likes the 90 gr Sierra HP & shoots it to about the same point of aim as my hunting loads. If you want a little extra speed, use the faster powders like 4320 or 4064. Modest loads give me about 3300+ fps out of my model 700 Rem. You can make them go faster, but I never thought it necessary. I have used "normal" 270 powders like 4831or RL 22, and a case full results in velocities around 3000 fps, or a bit less. Accuracy was still good to excellent.
