I used to be the national sales manager for a company that manufactured steel targets. They need to be set up a certain way and used with certain kinds of ammo, which is why we only sold them to the military, law enforcement agencies, and certain qualified individuals. The average person is way too stupid to be trusted with that kind of equipment.
A couple of weeks ago I was at a defense industry event, and for the live fire demonstrations one vendor set up a steel target to be shot at POINT BLANK so he could demonstrate his whiz-bang frangible ammunition. I didn't know him or his product, so I promptly moved my demo to a separate range.
