I tested them a while back. They are all super tough and create a lot of damage. These are big heads and you will need a good bit of fletching to control them, and they are not for high speed setups. They are however great for lower speed rigs and for those wanting a simple super tough easy to sharpen head that cuts a big hole. The 125 grn version is sort of an exception as it shoots well with 4" fletch and penetrates great.
