I've only run federal 210M's and I have no complaints. That's been with H4831sc, Retumbo and RL26.
What has been your experience with R26? Accuracy and velocity wise?
I don't remember what it was with the 4831sc, Retumbo was 2840's groups were in the .2's. 60.5 grains of RL26 gave me 2950 and groups that were sub .2.
