I made my first blow gun from a Mother Earth article and my darts for it came from the same article. Since then I have bought many with their wire darts. I have them in .40 cal and .50 cal. When in the Air Force we wasted a good bristle board shooting wire darts at it and playing 301 or 501 range 20 feet and I think 48 inch blow pipes. I also shoot 6mm airsoft BBs at targets at about 10 feet. I actually like to shoot blowguns better than slingshots.
