Dr. Fackler has a VERY low opinion of the round.

Pretty much its only claim to fame (and design criterion) is the ability (with ammunition you can't buy here) to penetrate an '80s vintage NATO steel pot. I've read a lot of robbery and self-defense stories here, and in not one of them did the mugger, carjacker or school shooter wear a helmet.

As for me, it does nothing I need done in any way in which I want it done.

It's nothing more than a very expensive way to shoot rats at the dump.
