A very interesting experiment with the use of various firearms.
Look, what will happen to the helmet when it is shot from a distance of 25 feet. Lessons learned:
1. Pistols are pistols and rifles are rifles.
The rifles had no problem penetrating at these short ranges.
2. We were surprised that the 9mm, .45 ACP, and the .357 Magnum were stopped by the helmet.
3. The 7.62 X 25 seems to be the big penetrator that we heard that it was. We're going to have to shoot this one some more.
4. These helmets were tougher than I would have thought. They're not designed to stop pistol rounds, but seemed to do the job just fine.
