I've seen one shot at 10m when it was attached to a 2'x1'x3" block of wood and it blew the wood to smithereens (admittedly it was a very old dry piece of wood), but trying to set one off with a screwdriver :?

:lol:
I've also been to a clay flush shoot where there were penalty birds and when shot they gave a coloured p**f of smoke, they weren't the same thing!
Reactive targets are always more fun to shoot but as has been said, they're probably not worth the money to do more than a couple of times. Unless of course you didn't pay for them
