I wanted to let everyone out there know the reality of these broadheads that Steelforce makes. They are ground from .080 titanium and then added a steel ferrule to fit for a custom broadhead. Nick at Steelforce sent me this aircraft aluminum 1/4" thick plate that they tested three broadheads from. All three are 145 grains using a aluminum arrow from a 70lb compound bow and still intact and ready to hunt with.
From left to right, 145gr phathead penetration that has a slight bump on rear of plate, the aluminum arrow shattered on impact.
Next is single bevel grind 145gr penetration with a broadhead penetrating through the plate slightly and aluminum arrow shattered.
Last is a double grind 145 grain penetration with pass through plus 1/4" and the aluminum arrow did not shattered, still intact.
Now with this info I believe that STEELFORCE BROADHEADS rank at the top of my list. Now that this study was done, what other broadheads can do this and still be able to go out and hunt with the broadhead.
