All I can tell you so far, is that it killed the target I shot it at. I bought some recently for bear hunting this fall. They shoot fine and seem to be very strong. The only drawback is the way of getting the blades apart. It takes a special tool. I don’t know that I would buy any more just because of that fact, but they do seem to be a good strong head. Also, they are one of the first cut on contact broadheads (that I have bought) that truly come sharp enough hunt with right from the package.
