We had the most luck with IMR7977 and H1000. IMR8133 was a tad slow for our rifle with 143ELD-X.
Here's an article we wrote for a local outfitter that goes through H1000, IMR7977, H1000, IMR 8133 and RL26. Lots of folks have great success with RL26, but our rifle got pressure early. http://www.rockymountainhunting.com/b/reloading-for-65-prc.html
We hope to try RL23 and H4831SC this summer too. Perhaps with 140 Berger Elite Hunters or 130 gr Sierra Tipped Gamekings.
