why shoot the flare out of the gun to ignite it, the one (and only) time I tried that it ricocheted off the floor and shot 150m across a field before lodging in a bramble bush! There after I've always dismantled them and used the contents of the flare to start fires (you can get more than one ignition from each flare that way too). .
