RL26. I have posted up the load and ladder data in couple other .277 threads. I will try to locate them for link but it is recent. There is no doubt RL26 is for sure the "pixie dust" for the old .270Win! The 145ELDX was screamer too. Right now the 2 bullets I am going forward with is the 156HH which I think will be stupid fast or the EOL.Yowser! Care to share powder you’re using?
