RE: Mechanicals for Bear?
If you are going to shoot a mechanical head I would say go with a cut-on-impact head. I shoot the Scorpion XP's made by NAP. They are great heads. You said you shoot shockwaves, well this head is exactly the same as the shockwaves, the only difference is it has a cut-on-impact head. I have shot a couple deer with it and it has performed flawlessly, but the most impressive thing that this head did, is when I shot a bobcat 2 weeks ago. I shot it in the neck and it made a hole the same size on the entrance as it did on the exit. I could put three fingers all the way through his neck. A bobcat is a very thinned skinned animal and for the entrance hole being as big as it was, the head had to open extremely fast. In fact I don't think you could ask for it to open any faster, I would compare them to any mechanical on the market in that aspect. So, in my opinion, I would go with the Scorpion XP's, they are sharp, accurate, and open very, very quick for a mechanical.
