Put a grain of pure sodium in that hollow point and seal with paraffin. Be very careful to not get any moisture in it (big explosion). Aim for center mass and as a general rule, arms, legs and head all go in different directions.
This is also very unlawful.
I like to take a hollow point and file an X in the top, then fill the hole in with mercury, then sodium, then a kitten, then a rhino horn, then cover it with baby seal skin. I put this all in a press and then skoosh it down real good.
Then I coat the bullet in Gelinite and then teflon. Now I drill out the base and add a rocket engine and a single Pez from my Batman dispenser...
