The way it seems to me is that propane and pnuematic cannons are reaching their upper limmits in power. Sure a more powerfull fuel could be used, but thats another story. Im sure there will be small advances here and there, but the pressure limmits on PVC have been reached. Maybe im just a pessamist but....

The biggest area of untapped potential lies in the ammo. From what ive gleened from various military tech websites and the like is that a large diamater, lightweight projectile accelerates best. Where as a dense, aerodynamic projectile flies best through the air. Enter the sabot.

The gun that I am designing is being based around the ammo. It will be a small, hand held or shoulder fired hybrid. The barrel will be 24" of .5" pipe or smaller. The part I need help with is what will be the best ammo.

I dont know how economical/feasible it will be to build many tiny sabots. So, even though it is best, I will most-likey just have ammo that seals the barrel.

The best i have come up with is a bolt and nuts holding 2 teflon washers that will seal the barrel. More weight = more momentum = more damage = better.

Any ideas are welcomed. I am will to pay a few dollars for ammo if it is devistating. Being that this is a hybrid, dense projectiles can take advantage of the power.

thanks in advance.

I shoot Gatoraid bottles....in season.

It blows me away....they start tumbling right out of the barrel.

You can hear the bottle tearing the air on it's way down range.

If the projectile flew flew straight...it seems to me it would fly further and faster and be more accurate.

Well, maby not. The bottle wants to take the path of least resistance, if it tumbles that may mean that the perfectly streight path isn't the most efficient. But what do I know you should ask D_Hall. That is his job, is it not?

but a rod is going to tumble. which is also going to be the problem with my ammo now that i think about it. is there an easy/cheap way to put fins on? Rifling would be the best... but that would be quite difficult.

Why get so complicated? Use shotgun wads. About .02 each. Paintballs are available at 1/2 inch and the standard .68 caliber, and paintballs can pass through plastic 55 gallon barrels. Dowel rods with steel washers on the front to create a slightly nose heavy balance. Think of an arrow or javelin. Experiment with length to acheive proper flight. On the Burnt Latke site we see dowel rods penetrating 500 pages of a telephone book. Imagine what larger diameter stuff would do?

The design work's already been done for years now by countless individuals making anti tank shot to be fired from smoothbore barrels.

Do you by any chance know someone that will lend you some uranium to machine? Other than that I would find a way to rifle your barrel and use a boatail type round that is tapered at the tip and about 2-3in long
