I would also add that it really is important where the brush is. If it is within a foot of the deer and it is just a little twig, you can shoot right through it and the deflection wont matter. If it is farther away from the deer than that, then you cannot shoot. A slight deflection 20 feet from the deer is a not only unethical in my mind, but also unsafe. I agree there is no brush buster out there, it is a total myth. Funny how many guys are chiming in with XXX grains, etc.
