Bumping this with a range report. Was getting north of 2900 FPS (2945 average) with just 56 grains out of my '81, 24" Model 70 Supergrade. No pressure signs of any variety, nice rounded primers. Got a tight MOA group with 55 grains, but it opened up to 1.5 MOA at 56. 56.5 grains is next on the list when I get back to my press
