I did not have any luck with RL 26 or H4350 in 6.5 Creedmoor. But I also had issues with Aliant and Hogdgon with 5.56 load development. Switched to Ramshot TAC and I have a load that gives me a 13 FPS ES. I hope that the Ramshot Hunter that I picked up today gives me better results.
Thanks for the info I appreciate you sharing it. I have Hornady 143 ELD, Berger & Sierra 130 grain bullets to try out.
