Very interested in this thread! I have a 270Win and shoot the 129gr. LRX and a 243Win and would love to have 1 powder to load both cartridges! I’m currently trying to do it with IMR-4831 but have yet to shoot my loads.

RL26 makes my 270 sing with 130’s and 150’s. I tried many other powders, including the old standby H4831, nothing beat RL26 from an accuracy or velocity standpoint. I have also heard it does very well in the 243. There was a thread on here a while back with a lot of folks recommending RL26 with either the 95 Gr partition or ballistic tip in the 243, depending on game hunted.
