I bought a Morrell Bone Collector Double-duty 400 fps broadhead target for the Tac15, and have not been all that happy. I'm shooting the crossbow side, and it will not stop arrows adequately. Even when brand-new the arrows would sometimes bury all the way to the fletching, messing them up and leaving me nothing to grab. Sure I could push them through from the back side just enough to get hold of the shaft, but this is really just not satisfactory. I'm now looking at a 450fps target sold by G&S Archery called the Hybrid Cube. It has a rotating core, and the core can be replaced. Sounds like it might be the hot set-up. Anybody used this product, or another BH target they are happy with?
