Nosler's numbers have always been high in my experience.

150 ABLR w/ 4831SC
Max load=55.0 @ 2,905 FPS
My load=58.0 @ 2,844 fps

140 NAB w/ RL-19
Max load=55.0 @ 3003 FPS
My load=57.3 @ 2954 FPS

Hornady seems right though,
130 GMX w/ 4831SC
58.1=2,900 FPS
60.1=3,000 FPS

My load= 59.0 @2946 FPS

Who the hell knows....
