I'm not going to get in the live bomb debate, seems a little risky to me. Read where a guy loaded his B-25 with "live" bombs, when he released them over the runway they exploded with far greater ferocity than he expected and it startled him so much his B-25 continued on it's slight nose down path right into the ground! lol

Anyway, I make *simulated* bombs. As far as having them pop apart on impact, haven't worked that one out, never thought about it really. The best material to load one with is barbecue pit ashes, it really makes a cloud. I'd like to try it with one of my 1/7 scale 1,000 lb bombs because they can hold a lot of it for a nice cloud.
