My bud and I saw this, and the problem that we've had is getting enough info on the round to build an -accurate- version of it. You really can't base it off the .50 Magnum Research Desert Eagle, because it's a totally different bullet, both in weight, and in velocity. If anyone finds both the velo and energy at both muzzle and range, I'd appreciate it, but so far, not even S&W has given that info. And it doesn't seem to show up on Winchester, Hornady, Speer, or any of the others that I check...
