Post,
Thanks for the replies with regard to powders and pressure signs.
The velocities were (to the best of my memory):
335 gr:
50 Beowulf ~ 1750 fps
500 S&W ~ 1720 fps
420 gr
50 Beowulf ~ 1520 fps
500 S&W ~ 1540 fps
Some of the 50 Beowulf brass was showing a concentric ring all the way around the web, which I was told was due to excessive pressure. Does that sound right?
