Styrofoam ball cone substitute
Posted 19 January 2013 - 11:55 PM
First, I picked up some rods that are used to make flowers, but of course they will be darts in my hands.
I found some styrofoam balls the perfect size for my .50 cal BG and was curious to see if they will work out.
Well they work quite fine. I am not sure yet, if I can say they are better than cones, but I can say they work at least just as well. (For spears at least)

Hmmm... I bought a bag of marbles at the dollar store. There were about 50 of them between .61 and .635" sizing was not more consistant than that. Anyway I selected ne that I thought was reasonable and weighed it 82 grains. Similar in weight to a .625 stun dart. Performance through the tube was close to half the speed of a stun dart. Watching the trajectory was easy and painful. I seriously doubt a ball shape in the tube is close to as efficient as a cone that fits as well.
Or, it's just me.

OK, Closer analysis...
I plugged the mouthpiece and started dropping marbles down the 5 foot tube at approximately 45 degree angle.
Of the 81 marbles in the bag I bought
3 were oversized.
12 were close enough to the bore size that they took over 5 seconds to roll to the bottom of the plugged tube. These are select ammo for the purposes of this evaluation.
66 were small enough that they slid down the tube faster. If I had set a 3 second limit I would have probably twice as many as my 12 select marbles.
I shot two select marbles at a cardboard target 30 feet away.
They punched two layers of cardboard which is a bit better than typical performance for a stun dart in the same environment.
So, in review, I got 12 or more good marbles for blowgun ammo from the bag and the rest will be reasonable slingshot ammo.
After testing in my 5 foot CS .625 I tried to test with the 4 foot CS professional .625. The professional has a smaller bore and only would pass 8 of the marbles. Something worth noting.
Never trust a first impression.
Your dollar store marbles may be differently sized, etc.
