That's why the pistol is on the left shoulder strap. It wouldn't kill him....but, it's better than the stick! Bear spray would be better and I carry it on the bike, just haven't found the right size to carry on the shoulder strap...yet.
Aside from the ethical issue of wounding an animal you intend to leave in the bush, there's the practical issue of have you deterred him, or just really pissed him off? And if not you, is there someone else coming along that you've just set a trap for? Hmmm.
