Head shots are tough, and most shooters are trained to aim for center mass.
This works well for normal self defense situations, but what are you going to do when you’ve got a mixed environment with “friendlies” and “thralls” and you don’t want to risk rounds punching through your targets.
The Hexolit32 may be just what you are looking for. The round will devestate anything it hits and you can aim for center mass. You will essentially be decapitating the undead by removing their torsos.
Watch the video and you will see how the penetration is just about two water jugs. Because the round opens up on contact it expends most of its energy in a very violent expansion on first contact.
