Re: Home made "exploding" targets?
It is said Roy Weatherby used to shoot 5 gallon (metal) cans filled with water to demonstrate the effective shock of his 300 magnum cartridge-- I have done this and it is very entertaining.
I have a target made from a piece of 1.5" plate, 48" across, with a 13.5" hole in the center; welded some small angle iron in a "V" pattern on the lower rear of the center hole, and place damaged 16" or 18" floor tiles sourced from Home depot in them. Paint the back of the tile red, the steel portion gets a new coat of white every few months, and the tile explodes on impact. Not quite as dramatic, but no doubt if you hit the tile center of the target.
