I have tried RL26, H1000, IMR7977, and IMR8133. The RL26 did give good velocity but living in the Phoenix area I tested it's temp sensitivity from March through June and loads that were safe in March have shown increasing pressure issues as it warmed up. So, all of the others have good accuracy with H1000 being the best. I was easily able to exceed 3100fps with the Berger 140 EH. I have landed on the 156 Berger EOL for hunting using H1000.Has any of you come up with powder favorites for loading 6.5 PRC using 140gr class bullets?
