I got a tin of these to play with...i very seldom kill stuff, but hollow points are iresistable.

Looking at them up close i was dubious about their ability to expand, there just isn't very much cavity...
So i decided to use my Quest (~15 fpe) to shoot one into "Silly Putty".
Now mind this is just a couple inches from the muzzle, but it does show true expansion to about .20 cal, and interestly the pointed part of the "PHP" is still pointy.
