I agree RL26 will give the highest velocity with 140gr or 150gr 270 bullets. But I think I get a little accuracy with
Norma MRP in the 150gr bullets. With the 140gr bullets my most accurate load is with RL23 at about 3050fps.
I can get 3125fps or so with the RL26 and MRP. Superformance also gives about 3050fps with the 140gr bullets.
