The kids called me the other nite a coyote attacked one of the dogs right close to the house on the farm the other dogs chased the coyote off so yesterday morning I went out with the son in law and grandson with the caller and guns, we set up on three fields that had a swamp between I turned the caller on to the coyote challenge for about a min and then listened and then turned the challenge back on and a coyote came out of the brush about 100 yds away looking at the caller and the motorized flag on top it came straight at me walking and turned just as I was letting a round fly to drill it in the chest with the .223 55 gr varmageddon hit the dog back near the last rib and it fell like a rock totally dead not even a twitch the varmageddon must of exploded in the dog there was no exit wound.
