1. the government says they are safe, and as cast they show very little radiation
2.every other government In the world is complaining about the usage. because..
3. I watched a video on these. the projectile was inert as cast, they fired it at a tank, it easily penetrated the armor, showing flames around the penetration, a hole about 3" in diameter, with burnt areas around it. the fella them took the same geiger counter to the hole, and it went crazy. the heat and friction reactivate the "dust" that scraped off as it went through. guess they also make individual rounds for armor penetration for rifles, but too expensive normally. what a great way to get rid of radioactive waste, shoot it at someone else
I have no idea how one ended up online for sale, but the shape is definitive, and his 1" rod 12" long weighed over 80 lbs. anyway won't post on this again, because thats all I know:). Just one of those things I hope future collectors won't be bringing home
