I did the same thing during deer season. I kept running into coyotes instead of deer. Once I was set up on top of a hill, I had my bipod extended and my dad was going to push the deer out of a bush towards me. The only thing he pushed towards me was a stupid coyote. I shot 3 or 4 times and missed each time. He came in from 180yds to 50yds! He did the same thing one day before and had nearly got his head blown off by friend's 7mm STW. I had seen the coyote three days before as I was walking through a bush. He jumped out of bush 20yds in front of me and disappeared before I got my gun up. He made no noise whatsoever and ran through the thick bush without knocking the fresh snow of one single branch. I'll get him next time though.
