I don't know what the big mystery is. The 5.56 FMJ bullets were designed to tumble and create large wounds. When Mig25"s buddy shot the dogs with them, that's what happened. They tumbled in the dogs and killed quick. Not my first choice for any hunting application, but they probably would kill dogs consistently.
Gatehouse - Now that is VERY interesting ! I have not heard of that before - Learn something new every day ! So the 5.56 FMJ bullets were designed to tumble ! Which exact bullets would those be - any brand factory loaded with FMJ ? Would a Horn .224 FMJ bullet loaded in a 223 or 22-250 tumble inside of a Yote do you think ?
