I made some wax slugs a few weeks ago and finally tried them earlier today. It was just wax I poured into 3/4 CPVC pipe (same as my barrel), and pushed it out.
This is pretty cool ammo. It's hard enough that it stays together nicely during flight, shoots through thin sheet metal, breaks glass bottles, but it just breaks into peices when I shoot it at a metal trash can or a brick wall.
It may not be the best penetrating, but it works great here in the city. And I don't have to worry about running over it with a lawnmower if I lose one in the grass.

I made a couple 2 inch diameter ones with chain and random metal bits inside the wax for my combustion, since they will just land in the corn field (where I will retrieve them to shoot again) or in the woods, so it won't matter.

i like taking a piece of pvc pipe that is smaller than the barrel and heating one end of it up. i use a blowtorch. then once it is heated and it gets soft immeadatley put it on a funnel. this will make one end bigger so it will fit and stay at the end of the barrel. now you take the other end and tape it with duct tape to close it up.

How about 2" steel tubing, weld one end on it, fill it with almost full with steel shot and weld the other end on it. grind it smooth and have fun. It is reusable.


Also if your feeling brave try a 2" trailer hitch ball. Kicks like a mule and does devistating damage.

I like my paper mache rounds, especially for gooing ppls cars

newspaper waddind tp roll and little freezie bag inside the roll full of flour and water. Splats ever so nicely and is a bitch to clean off when dries:)

Best luck I had was with a fat bolt with rubber seals on each end.

Wish I had a good pic.

Take a bolt, slide on in this order

- metal washer (smaller than bore)
- rubber washer (slightly bigger than bore)
- metal washer (smaller than bore)

- Pipe Nipple of appropriate length (wrap tape on bolt to center)

- metal washer (smaller than bore)
- rubber washer (slightly bigger than bore)
- metal washer (smaller than bore)

and screw on the nut.

It works great because the seals get every last bit of energy out of the gun. Mine weighed a pound and went *through* a 22" computer monitor.

We made a damage video: http://klugeboy.net/Movies/777HighlightsLarge.wmv

That vid is very very nice!

My idea:
Havent tried yet but I was thinking of a foam sabot with a small but long steel pointed and sharp pin in front of it.
The idea is that the sabot gets pushed VERY hard by the pressure on the whole back surface and the pin gets almost all the kinetic energy since almost all the mass is there.

Now when this exites the barrel, we have a pin with kinetic energy in it as much if it would be the whole barrel size. The foam sabot has almost no kinetic energy and is left behind.

Now when it impacts, the whole kinetic energy impacts on the SMALL surface of the diameter of the pin, and not of the whole barrel diameter.
In this way it should be able to penetrate WAY HARD.

The 2 points this idea is based upon is:
-Surface area of pressure force propelling the mass
-Surface area of impact force that makes the hole.
The bigger the barrel diameter, the bigger the surface pressure propelling the projectile.
The smaller the impact surface area, the more kinetic energy is slammed in per square inch or cm.

Im going to build it soon.
What do you guys think?

i sometimes fire used AA batteries with a nail hot glued to the top, the battery doesnt rele stay on the nail upon impact, but it gives the nail the momentum to do some serious penetration. i usually sabot these in toilet paper so i dont get a nail stuck in my barrel.

My penetration ammo includes a metal rod filed at one end.

By far my favorite

Something destructive would be 2 steel balls with chain linking them together, i can imagine that would tear a large hole in something.

That sort of shot has been used centuries ago in ship's cannon, in order to tear down opposing vessels' masts and rigging.

But I doubt a firecracker would do any damage to the plywood.
Firecrackers are loud but they are not that destructive.

If simply detonated on the surface, fair enough, throwing a little kinetic energy into the mix changes the equation. Unfortunately some variations on the theme are familiar knowledge in Iraq...



though again, this is beyond the scope of discussion of this forum.

Well Jack, you beat me to telling Cool about the mast destroyers.And good having you back.Things got rather boring without the master "Googler"

Well heres the link to the chain shot:

hehe well I figured I would have much time to go online when in Spain but I have limited net access at work plus a couple of hours at an internet cafe in the evening, people go out drinking pretty late here anyway so yeah, I'm keeping up with the forum.

Sorry, I wasn't aware of the limit on what you discuss. I'll only say that there is a way for a firework to damage like that, but that is all I'll say, that and that I apologize for posting that, I guess I'll have to read the rules a bit more thoroughly

it's no biggie.

this thread has been going for quite a while.
