It's not a new concept. The same thing has been done in several different variations over the years and they usually fade away after a couple of years. The laws of Physics are pretty much set in stone, so every time someone comes up with a new whiz bang way to defeat them, they trade off something else.
I'll just stick with the old tried and true bullets that I know will work and hope that I never have to actually test them in a bad situation.
Hope this helps.
