Maybe in the states they can get their jollies off of them, but up here, having experimented with similar 6mm, 8 & 9mm types, they're garbage.
When I worked in the film industry, they used paintball guns to shoot "paintball" filled with that explosive stuff to make sparks on walls. Thoses where much cooler than those 6mm balls.
