I don't know. That comes back to my arguement on Traditional Archery Forum (Who hunts with Indian Bows), I was suggesting I could use arrowhead poison to kill a Deer with my bow, or shoot it in the neck to bleed it. Didn't work out with the other guys, they went crazy mad and taunted me and stuff, pretty funny. It could happen though. Anyway, I personally think at close range a 30# bow can kill a Wolf. But thats my opinion. I just see that if you hit it in the vitals up close (15-20) feet, the arrow should drive through at least 5-6 inches enough to kill it. All about shot placement. But that would be hard. Tommorow im going after some Cottontails with my bow again, I just wish i had someone to hunt with. No one hunts around here that much. For tracking the deer within 3 weeks, i doubt i will find it. And besides the meat would be spoled and stuff.
