The 75mm HE shell, while a fix round, came with three different charge levels. A reduced charge with 0.59 lbs propellant, a normal charge with 1.15 lbs and a super charge with 2.00 lbs. I don’t have the MV for the reduced charge round. The MV of the normal charge is 1470 fps, and 1885 fps for the super charge round.
