my issue with these types of ammo is the same as it was 20years ago. Simply put, the likely hood of through shot shrapnel is so increased that i would not use it in defense. I want those shots i put on target to impart every micro joule of energy into my targets body. Watching this vid i see way to many minor projectiles leaving the target gelatin. I would rather see this round fold over like the gun crafter industries copper hollow point.
As for piercing armor, heavy clothes etc like they claim, then why the hell did they not show that in the vid.
Sadly, this is again a case of people looking for technology to compensate for poor training, skills, and poor practice. These things are 99% of what we need for defense. The bullet, is not even the remaining 1%.
