Jhodge is exactly right. This ammo was developed to stay in its intended target for CCW folks. Limit ricochets and any pass thru fatalities. Supposed to deliver full foot pounds of energy into the bad guy and fragment into pieces and deliver a nice wound channel. I youtubed my caliber(.380) and found out it didn't fair so well in ballistic gel. However the larger calibers did do what they claimed. I also found that the guys shooting steel targets love the stuff for obvious reasons. I picked up a box of DRT .380 85gr HP and will run them through my Sig. Gonna experiment on my own.
Life is a rush into the unknown. You can duck down and hope nothing hits you, or stand up tall, show it your teeth, and yell "Dish it up baby, and don't be stingy with the Jalepenos!"
