hc, what you don't know about the last post has built an industry. What training have you ever had and what experience on ballistics and ballistic tolerance? Stop the bull, please.
Your crackpot theory about "mach 3 bullets" makes no sense! First off, do you actually think the folks who made the 23mm didn't want it to do any damage? It is designed to shed its maximum energy into the structure it strikes, like a hollow-point bullet! Secondly, the 23mm that the blade is designed and tested to withstand is a High Explosive Incendiary (HEI) and the energy of its explosive content is not included in my brief discussion below.
Again, you have no idea what your are talking about, none, zip squat. Time to just quiet down, cut the caffeine and learn something from your peers (I use the term "peers" term very loosely here.)
BTW, I sent you a Christmas card, did you get it yet?
