338shooter, obviously I don't get around here much, LOL. I am running RL-17 simply because I can't find H4350 around here. I haven't shot this rifle a ton but I have shot some nice groups (for me anyway) with the 140 Bergers and 140 Accubonds. I found an accuracy node between 42-42.5 grains.
The groups started to open up after 42.5gr and started to close back up at 44gr. I started at 40gr, which shot like crap. I started at 40gr because I was reading a lot of people having pressure issues with RL-17. My gun showed no excessive pressure at 44gr, though, and I shot 44gr with 140 Accubonds at 88 degrees. I don't currently have a chronograph, so I don't have a clue as to speeds.
I plan on loading some rounds up from 44gr and see if the groups keep closing up. 44gr was right about an 1.5" for 3 shots while 42-42.5 could have been covered by a quarter.
