close
the two rounds that are going to be the closest to what I need I think are the 500 a-square, and the 50.-460 bushman. neither are exact, but I think the a-square will come the closest to being correct. the one thing I have realized is this thing is gonna be heavy! Even with a barrel length of around 20 inches the rifle is still gonna weigh about 13 pounds. But the calculated muzzle energy is unbelievable. supersonic this thing will be about 90% of a .50 bmg. i don't have the calculations for sub-sonic yet but they should be pretty good.
