You know I can actually tell you that... but I doubt you will get 200 fps with this particular bullet. With a 300 grain real possible...
I will go do some computing....
OK with this bullet @ 2100 fps second you would have 2154 #'s of energy at the muzzle.... If you could get it going 200 fps faster the energy would be 2300 #'s of energy. After that the bullets BC would detirmine down range energy.
Now with a heavier bullet... like a 300 grain bullet shot at 1900 fps second with T7 the energy would be 2405 #'s of energy and then adding 200 fps the energy would be 2900 #'s of energy.
