I recently tried some 300 Gr. Noslers. The new .451 HG partition.
Using 30.5 Grs of LG -- Average Velocity -- 1826 fps, ES - 74 fps, SD - 30 fps
Using 31.0 grs of LG -- Average Velocity -- 1853 fps, EX - 26 fps, SD - 10 fps
Using 32.0 grs of LG -- Average Veolcity -- 1883 fps, ES - 27 fps, SD - 11 fps
Results from other 300's using 30.5 grs of LG in the past were .452 diameter. These Noslers are .451.
Accuracy of all the noslers were in the 1 1/2" range (less than or equal to). There was really no difference at 100 yards to make a distinction. Using this bullet, I would opt for 32.0 grs. These loads showed no signs of pressure. 16" barrel, WSR primer and taper crimp.
RUNNING OUT OF PRIMERS!
