Somebody out there who can share his 577 NE reloading data with me? Thank you

I dont have any loadings of my own but A-Square published the following for 577 NE using 750 gr bullets:
1)H-4831, 153 gr., 1925fps, 27600 PSI
H-4831, 157 gr., 2034fps, 28700 PSI
H-4831, 163 gr., 2128fps, 34600 PSI

2)IMR7828, 160 gr., 1889fps, 31200 PSI
IMR7828, 165 gr., 1967fps, 32200 PSI
IMR7828, 167 gr., 2071fps, 34100 PSI

3)RL-15, 132 gr., 1980fps, 21100 PSI

I don't know anything about these loads but they are a starting point.
