I just emailed the company, and haven't gotten a reply yet. I have one major problem with this and that is that the 20mm ammo used in the Air Force's Vulcan Rotary Cannons, are ELECTRICLY PRIMED. I spent a few years as a bomb loader on F-16's and A-7D's that used that ammo and we had to ground our selves before touching these rounds to prevent the possibility of setting them off in our hands.

These rounds take 28 Volts DC to go, and it is possible to build this charge in static if conditions are right. When stationed in Korea, one of the guys pocketed a round and took it home and put it on his TV. As soon as he turned the set on, the round detonated and took off the top of his set. He was lucky he had a remote.

I'll post more when I hear back from the company about this. They may be using another type of ammo, but according to the site, it is the same as used in the Vulcans. This could be a bad thing.
