Ok I know we all debate the "weak" stopping power of the 5.56. Well count me in as a full supporter of the 5.56. We just had a meat packing facility here in the city lose a large pissed off steer. They called in a panic as it was running through the city with a lot of pedestrians out. I was enroute along with several other guys. I was wondering if my dept .223 would get it done, as they were asking for PD help in putting it down. As I pulled up, two of our detectives and SWAT guys were out. I hear a crack and realized that a 5.56 had just been sent into the steer. It staggered it real good, then a second or two later the second round hit and the steer tumbled and did not get up. Distance was prolly about 50 yards and I am not sure where the rounds hit. My point is, if that would drop a 1000 pound steer, I feel confident that it will do what I need it to do on "other" targets.
