I have tested them, not the new improved ones though. They are a good head, accurate, sharp, and they open fast. The body of the heads is a little weak, as it will get dented, but it doesn't effect how they preform. The penetrate well, and should be deadly on game. I have heard they did some improvements on the main body to strengthen them in that area.
