Honestly, there are plenty of similar YT videos on other 9mm ammo that look just as impressive.Check out the damage the 9mm round does to this store bought unfrozen whole chicken. http://www.youtube.com/watch?v=eWINwccJ37U
They will be banned soon.
It retails for $ 44.00 per 20 rounds.
Or 357 SIG.
1400 to 1600 fps for a round weighing around 90gr. That'd level some serious hurt on something.
Overpenetration is definitely going to be a concern though.
seems to me this would be less likely to overpenetrate than ball/fmj. lots more fragments with plenty of surface area to transfer KE to the target.
