Its not impossible but I think luck plays a big role but then again isn't luck part of hunting. I got one monster coyote this fall. He was 60# and I am having him stuffed. I had seen about 8 deer does and young bucks come bolting across a small field in front of me where I hunt and couldn't figure out why they where running at full speed. Moments later came the biggest yote I had ever seen. So I gave him a fawn bleat and he came running straight at me. At about 10yrds I hit the grunt and he slowed down. I pulled back and let it fly. Clean kill 10yrd broadside. Funny, they sure don't have the same ability as a big whitetail to haul ass after taking an arrow in the chest. He went down in about 15yrds making some strange noises just before he expired.
