Had great success with W748 with CCI250 primers and WW or Remington cases. Start out with with low charge weights and work up. If you have a chronograph you can match some of the velocities in the loading manuals. The Hogdgon manual #26 gives pressures for 130 grain bullets with several companies powders.
Remember though that not only is your rifle probably different than mine, your primers, powder, are all different in lot # than mine. So YMMV (your mileage may vary)
