Make sure you seat them .050 off the lands, not just shy of the lands. Don't ask me how I know.
If you do that, most data for other bullets should be pretty close. Work up, and see. In my '06, 61 grs. shoot really well with the 155 Scenars.
The other thing is that brass can vary and so can the best, or top loads. So, work up. I'd start at 57 grs. and see how they shoot. E
