I too have a Ridgeline in 6.5 PRC. I have some 144"s and 153.5's I haven't tried yet. I have tried 156 and 140's. RL26 and H1000 have worked well. Retumbo and 8133 not much luck with. I also have but haven't tried N565, 7977 ,H4831, RL23, RL33 and N570. I think BrentM is probably correct about RL33 and possibly Retumbo and 8133. N570 for sure. I have hopes for N565 , RL23 and 7977. Going through same testing with a Copper 52 in 6.5x284. same bullets and powders.
