RE: Open on impact broadheads
A hypershock is about 1.5 inches from the tip to the blade deploying tabs. So the blades go in about 1.5 inches then they open up. Now what happens if you happen to shoot an animal such as an elk or moose in the shoulder? You got about a half inch of hair, an eighth inch of skin, then about two - three inches of muscle, and finally about a half inch thick bone. It would seem that the blades should be open by the time they get to the scapula so my questions are................ How will the hypershock fair getting those huge blades through the scapula and into the vitals of a large 800 pound bull elk or 1500 pound moose? How much energy would be required to push a 2 - 2.75 inch cut head into the vitals through this kind of shot? Would the blades hold up well enough to still cut the lungs on a shot like this if they did get through the scapula?
Just honest questions looking for honest answers.
BTW, a broadhead, race car and air plane do not use the same materials in the same way. A broadhead must withstand a crushing impact, an airplane must withstand flexing and a one million dollar racecar is made of carbon fiber and not aluminum. The part of a race car that has to withstand a crushing impact (roll cage) is made of steel or titanium and not aluminum.
As far as a slick trick needing 2.75 inch blades it doesn't. It has four cutting surfaces extending out from the center 5/8ths of an inch each for a total tissue cut of 2.5 inches (.625 X 4 = 2.5). Larger than the 100 grain hypershocks 2" cut and just a quarter inch shy of the 125 grain hypershock. It cuts 2.5 inches of tissue all the time every time with out fail.
The 2.75 inch head didn't even have to cut anything going in and still didn't penetrate the back wall. The blades were not even deployed going through the first side of the steel drum. However I would like to see what they would look like if they did have to go through the first side. But that's not the design of the head.
