there is alot more to this technology that meets the eye,and I supposed that i could go into the rendition of why this is a good CQB round,and if I were to worry about an attorney,then citizens out there using the same type of technology would have to worry also I.E. glasser(leaves no trace for ballistics) The I.Q. bullet (also leaves no trace) just to name a few.But the way i see it is that if it is good enough for the Dept. of Energy and the Dept of Defense(which we got to sizable contracts from for Frangible ammo) thenI am not going to worry about my liabilities.
Lead works fine in a self defense load,however,you might want to consider putting a hole in it(Hollow point)
