This looks like it would be a superb self defense round - if you can find it.

The zombie ammo (z-max) is the basically the same thing as the V-Max.
Waste of good money. Buy the Barnaul hollow point ammo for your AR15 and know that the bad guys are not going to know the difference when hit with either bullet. I shoot piston guns and the Russian HP steel ammo runs fine in them. Chamber brush with CLP after a couple thousand rounds and it’s good to go another 2000 or 5000 rounds.
