“And, at 130 yards, it was probably still stable in flight (not tumbling), so it would tend to go right through the ear without tearing a lot of nearby tissue.”
Please stop with the magical/ mythical tumbling 223 BS..
A 223/ 556 is going to flu straight and true well past 400 yards.
Thank you. Even when a 223/5.56 hits a person, it doesn’t tumble. It may yaw and then break apart and the pieces may go off in a cone shaped pattern.
