This weekend at the camp a buddy of mine brought his AR-30 along with some exploding targets he ordered online. Needless to say they exploded a little more then expected. It is a small canister of white powder and it was placed inside of a old stove. He measured where the canister was inside the oven then closed the door and put a sticker on the door even with the canister. He set up at 50 yards(way to close) and shot the stove. You can see the destruction in these videos. Next time need to set up at about 200 yards.
