I was reading about these a bit ago and they're fascinating. For such an incredibly simple weapon, they sure do seem effective. I found some people that were hunting squirrels, rabbits, even fishing with them (same way you shoot for fish with a bow). So I had to give it a try. Naturally there's a lot more to it than at first glance!
I'm using a 3 foot section of old metal mop handle. Kind of short for a blow gun, but it lets me play for free (junk). Prototype 1 was just a wooden slug, basically a .30-06 bullet stretched out to twice its normal length. Doesn't work, it just exits the muzzle spinning crazily and goes about a yard. Prototype 2 was an elongated cone with a smaller-diameter tail, trying to get as much mass forward as possible. It went farther, five yards or so, but with no control whatsoever and still lots of spinning. Then I added some basic fletching. Prototype 3:

It flew point-first, but swerved a bit erratically. Probably my crappy feather.
Prototype 4:

Same idea. Enlarged head, tapered tail, but now the curves are much more gradual. I took a section of feather up a ways so it was straight, and made it up more like an arrow.

Now we're talking! <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> That was only from five yards, but I'm a newbie. It still doesn't fly perfectly straight. My feather is still lopsided and I could probaly do more whittling to smooth the shaft. But it's an order of magnitude better than proto3! It's surprising how much it penetrated the target, considering it's high density foam for archery pracice.
I'm thinking my next prototype will be of a denser wood (this is ash). I'll raid my stocks of seasoned fingerling oak. Logic suggests that the thinner I can make the shaft without compromising on mass, the farther and faster it will go.
Anyway. I'm just pretty excited by my progress here, thought I'd share and ask for input.
