What you need to understand with Rocket....or any tip to rear lever style head is HOW they work.
They are designed with one purpose......to be shot at hair, flesh and blood.
I've shot Rockets into a hard foam 3D target to confirm my suspicions, and they didn't open.......WHY? Because they are not designed to open on a hard non-flexible surface.
In order for the blades to deploy properly and completely they must first encounter a flexible barrier such as hair and hide......this forgiveness of the surface allows the blade tips to clear the outer most diameter of their swing and fully open.......
When you shoot a lever style head into something with no "Give" like foam, wood or steel the blades cannot lever around anything.....the blade tips simply are forced back into the retaining screws and many times blade failure is the result.
This is one of the reasons that this style does so poorly in 5-Shot's Plywood , Tire, and Steel tests.....but also one of the reasons I've had good success on solid bone (spine)hits with them: They went thru the hide and hair FIRST.
I will add also that the effect is exxagerated further as you increase cutting diameter.....One of the reasons (other than the tip) why the Rocket "Steelheads" perform Ok in these tests. They have a very small cutting diameter and a power style point.
If you want to see if they are truly performing as intended, hang a fleixible barrier in front of your foam target.....a peice of raw deer hide would be ideal, but you can get creative.......if they don't open then? I'll eat one.
And Greg.......still a week to go til' the bowseason starts and you had to break out the "Turkey Neck Story" already!? <img src=icon_smile_tongue.gif border=0 align=middle>
But Greg is correct.....if not redundant<img src=icon_smile_wink.gif border=0 align=middle>.....if it will open fully on a Turkey neck that's saying something.
