If I were you I would start pretty light and just watch the velocities on the Chronograph. I would be very careful of velocities much over 3100fps with 200gr bullets. If you find a load in the 3050-3100 range that shoots well it would be golden. If I were shooting that same rifle again with a new lot of Retumbo I would do the same and rework up the load. over 9yrs powder lots can vary. My new lots of H1000 are giving me much better velocities than before as just one example.........
