Quickload data says at 105% case capacity, it will get 3176 FPS with 54,708 PSI pressure.
This is with a Hornady interlock HP.
However it is a not data from actual testinh and i have seen duscreotincies in the liad dara on Quickload .
Their load book shows two powders that will get 3,200FPS.
H1000 and H4831.
50BMG is a very dirty powder and does not measure well, but if ya got it, use it!
