2" Projectiles

I use 2" bores, primarily to fire Nerf Pocket Vortex's at Paintball Tanks during Big Games.
Of course, like most of the people in here, it's nice to see what other projectiles can do, in the way of performance.

Do you ever find yourself trying to stuff small drink bottles and objects into different sizes of PVC pipe to see what might fit well? Sure you do if your a launch-a-holic! :D

I found that caulk tubes fit pretty nicely into a 2 inch bore.
Use a wrap or two of black electrical tape to give it a tighter seal.
Silicon Spray helps reduce bore friction.

A full tube of caulk weighs a lot, but one that is about 1/4 full to nearly empty has all the weight up front and a light tail. if they hit a solid object they can also Splat it with the last little bit of caulk in tube.

End result: I was able to shoot the used caulk tube through a 1/2" sheet of plywood. They aren't super stable in flight, so for longer distances they'll probably wobble a lot and even tend to tumble.

If there is a construction site nearby, and they are at the point where they are finishing and painting, you'll find used caulk tubes lying about, or in the trash piles and dumpsters. Always ask if it's OK, and NEVER steal full tubes, or anything from a job site.
merely taking away a little bit of their trash can't hurt.

And always clean up your trash (targets and projectiles) after a test session. This keeps the locals and neighbors off of everyone's case.

Anyone else have any good ideas for 2" Projectile fodder?

I use the caulking tubes as well. My combustion will launch those pretty well. Whenever somebody asks me what all I shoot out of my cannon, I just say "Whatever I can find that fits"

I was trying to think of a shotgun type projectile. Just put some wadding down the barrel, pour about 20-30 marbles in, and place another layer of light wadding on top of that. Kinda dangerous, but sounds fun. Could make for some good damage pics

I use a 2 1/4" hole saw, with the center drill bit removed to cut 2" foam plugs.

You insert a foam plug into the bore, then pour in your smaller projectiles of choice, then use another plug to top it off. Ram it down and fire.

Since the plugs are foam, they are deflected out of the way, allowing all the other goodies to go downrange. The foam lands about 20 feet away, and can be re-used for a lot of shots.

Cardboard TP tubes with a cardboard floor-disc also work too,
but using the foam plugs eliminates the need for a Sabot cylinder.

I'm trying to develop a PVC round with spring loaded stabilizing fins that deploy on launch, like a Tow missle. Fin stabilized rounds are very reliable, if you are trying to hit the same target over and over at a distance.

my favorite ammo for 2" is a sabot with water :D

How do you make the sabot with water?

isnt a sabot just like a milk jug cap or something similar, and then you just put water down after it?

The reason I asked, is, when I hear sabot, I think of a break-a-way casing. Like a cardboard tube slit in 2 or 3 sections.

Water balloons are always a problem, especially in a 2-inch bore.
We have been working on a sabot system for those small water balloons, but, part of the problem is the initial pressure wave during launching pretty much squishes the balloons and they come apart as their leaving the bore.

We are looking for a long range water balloon solution, so it bursts on target and not in the bore.

We've got one good "possible" solution, still have to build it and test it.

some one mentioned to me (all credit goes to this person) get a dowel rod the same sise as your barrel and attach a chain to one end.

Frozen limes,they go really far and if you have a lime bush/tree there is alot of ammo,i also like bunches of grapes they are quite cool but dont go far.One thing not to shoot is alot of oxide cemment colouring that stuff is near impossible to get out of things it stains really badly!

that's right, a pnuematic wouldn't need one would it? my bad, pnuematics are all i have :)

can't wait to get my newest gun finished, but yet i can because i am.

i'd have to use a 3" endcap as a sabot on my (in progress) gun.
