hey I jsut killed a big doe with my rocket wolverine 4P heads. at 17yds it was a complete pass through leaving a big hole on the exit, she ran 18 yards and fell over dead. when I looked at me arrow I noticed that the collar that goes on between the head and the arrow was broke by the blades opening. I also noticed that when the blades broke through the collar one of them also cut into my insert and arrow shaft itself.
did you notice anything like this during your testing of Rocket heads?
