I have the same rifle / calibre as you and I worked up a load with 140 AccuBonds, RL-19, WW Cases, and CCI 250 primers. I was hoping for more velocity though (I chrony'd it at 3080 fps), and eventually I found that the Barnes 130 gr TSX shot more accurately out of my rifle. As I'm sure you know, one guy's pet load may not shoot as well in another guy's rifle. I think RL-22 would be a better choice of powder, or Retumbo, or Magpro. You'll have to work up the load for your own rifle, but powders in the really slow burn rate are probably best.
