I have read that the M193 (lake city made for me) is actually designed to fragment in spite of NATOs restrictions. My understanding is that the bullet is light (55gr) and once it enters the human body it begins to yaw, and once it yaws to about 90 degrees and the resistance is greatest the bullet fragments. Other FMJ 223s and 556s don't do this as well or at all.

My question: would .223 JHP rounds (40-69gr) produce better terminal ballistics and be better suited for defense or would the Lake City FMJ M193 actually produce better results?

I suppose you really have to subscribe to the m193 being a reliable fragmenter. The argument's in favor of m193 is that it doesn't get clogged in clothing, it has far better penetration (will break bones whereas a light varmint JHP round might be deflected), and will fragment every time. However common wisdom has me thinking JHP for defense.

What do you think?
