http://youtu.be/AD4Z5hKg8zs heres the video with a lack of penetration for critical defense. On the other hand, in .45acp I can tell that critical defense was a better built bullet. The powrball were not all seated correctly some were deaper than others, ALL the critical defense .45acp were seated exactly the same.
FYI if your in jersey i think Hollow points are illegal to carry for sd.
