HW682 Posted August 24, 2010 Report Share Posted August 24, 2010 I assume you mean a muzzle energy of 30 fpe? (ft.lb energy) (Not just trying to be awkward...the energy is related to pellet weight and speed, so it is important to get the right inputs to get the right answer) Have to tried an online energy calculator?
