AA8700, start at ~95gr and work up toward 110gr..... .010" to .020 off the lands.
Load up in 1gr increments and let pressure signs and accuracy dictate. Fill in the gaps w/ .5gr when you see some interesting accuracy sweet spots starting to show.
Once you have the powder charge dialed in, adj seating depth to fine tune. Should realize about 3000fps.
Might also check data for Retumbo and RL25.
