I'll buy hollowpoints and practice.
It looks like it would make a nasty entry wound but it only penetrates 7-8 inches in ballistic gel.

IOW one notch above birdshot.
Beats a pointy stick I guess.
Thanks,Dan, you deserve a better answer so here's the short form. For defensive ammo, my only concern is making my attacker stop attacking. Pain or blood loss may make him decide to stop. Incapacitation or death will force him to stop. I need to cause as much trauma to him as possible in the fewest shots becuse I don't want him making a decision, I want to make it for him. Nothing in this ammo suggests to me that it will destroy my enemy's central nervous or skeletal systems any faster than conventional JHP's. Destroying those things is how I force an attacker to stop NOW. Blood loss means he may still be moving, and therefore attacking. I don't have time to wait for him to bleed out and pain is an unreliable stopper. In short, this looks like a gimmick that won't do anything better than more proven technology.
Interesting but I'm always suspicious of new wonder ammo claims. Most of the ones I have seen turn out to be just gimmicks, if not pure shit. That being said this particular one would be interesting to see in objective testing, might have potential.
MSP golfing buddy keeps telling me to pick HD ammo based on what a jury might see. He claims these special rounds put a notion in a jury's head for premeditation. no data on it, but I'm inclined to agree.
While its cool to think about, IMHO, I'm not going to shoot anyone with anything but generic run of the mill stuff.
