I was always 100-150 off with a 22" barrel. I now have a 30/06 with a 25" barrel, I get 3050 with 150's, 2960 with 165's, and 2825 with 180's. All loads are right at or below book max, and loads I have used in other rifles.
I have had my best luck with IMR-4350. RL 22 gives some great accuracy, though a bit less velocity. The 165's at 2960 are launched with W760, the first time I have tried that powder.
