Mathman, I've tried up to 47.5 varget with that load and start to see pressure signs. Also running out of case room. My velocity flattens out at 2800 so Im pretty sure everything is telling me it's time to back up. My SD and ES also show more variation. A load of 47.2 of rl15 does the same with velocity max around 2800. ES through the roof on this one. Power pro 2000 mr at 51.5 with a Nosler accubond runs 2875 but I'm getting slight ejector marks. Not to mention recoil and muzzle blast. This powder seems to come and go. Both with 165 and 150s. One day it groups well, at lower charges than the one mentioned above. The next day it's all over the place in groups and velocity. Temp seems to play a role in this. I'm going to back off on the h 4895 and do some experimenting I haven't shot enough of it to get a handle on it's accuracy. I'm just perplexed by the lower velocity of the other powders in this length barrel.
