You guys talk about spine like it matters-it was the first thing that I was taught to ignore. My teacher had a five gallon bucket of random arrows and we had to practice until we could shoot anything we found. Asian archery doesn't really consider spine at all, if it's the right length it'll fly. The technique was developed to shoot an enemy's arrows back at them. But with a thumb ring and the arrow pass on the other side I can shoot anything.
As to the idea of guns, nothing is ruled out. I haven't ruled out traps either. That dog ended up getting finished off, and I have had enough dog funerals this month. I'm going tomorrow to pay the game warden a visit and see just how far I can take this legally. If legal, I have a LOT of vials of heparin that I can dose meat with, all acquired legally (as my wife is on permanent blood thinners for a clotting factor issue.). I could see no regulation against it on arrows so long as it wasn't deer, but I'm not gonna touch the stock unless I get the OK from them. I could not get a solid law against (or that even mentioned it) and I want to find out if it's OK. Just a nick would bleed wildly, making those arrows a lot more effective.
You won't hear me supporting baiting deer, or using anectine on them, or any such, because I don't go for that. Deer aren't routinely dangerous, but coyote are, and they have no fear of humans. Think I'd like to try my new bow on them. But if it comes down to it I'll set out jaw traps full of heparin and let them bleed out. As you gentlemen know, it's war on coyotes.
