I think your refering to something that will make a mark when it hits like talc powder dispursing on impack.

Search the ammo thread!

Make your post more presentable next time. Your lucky I'm feeling nice today.


Here are the rules on this subject:

3 Discussion of solid propellants, explosive devices or incendiary projectiles fired specifically from a spud cannon is prohibited, and may result in a permanent banning of your account.For the purpose of this forum, these definitions will be used:
Solid propellant: Any substance containing all the chemical elements required to enable sustained combustion without the presence of additional oxidizers. This includes but is not limited to gunpowder, thermite, and many commercial and/or homemade pyrotechnic compounds.
For this purpose, nitroglycerine, though liquid, would qualify.
For this purpose, ordinary flour, though solid, would not qualify.
Explosive device: Any device that has the capability to release large amounts of stored energy rapidly.
Discussion of fireworks as projectiles is prohibited.
Discussion of "soda bottle bombs" or any other similar devices that may cause shrapnel as a result of uncontrolled rupture is prohibited.
Incendiary projectile: Any projectile that is capable of producing flame.
Rocket propelled projectiles, pyrotechnic smoke bombs, or any other burning projectiles would qualify as an incendiary projectile.

I'm a little worried by this - mostly when I see points like this popping up, there's a fairly high hit rate of someone planning to use them against people, a little like a version of paintball.

However, on the off chance that's not the case, I suggest the crude solution of filling a balloon with flour. If it's fast enough, and the target is hard enough, then it should create a nice cloud of smoke on impact.

Just DON'T use them against any person.

I know this isn't a rules discussion thread, but that's a very ambigous point.

A regular spudgun tends to release hundreds of joules in a dozen milliseconds or so.
A car engine can chuck out hundreds of thousands of joules in a second.

Both fit that loose description to a T, but obviously neither of those is against forum rules.

Well, Rag just gave you a grand idea- flour. Mix the contents of a glowstick in there and you're in business.

I'd say load it with paint, but I don't encourage vandalisim.

maybe use a thin schedule 1" pvc so it will break on impact. Or find a different tubing that will fit your barrel but is durable enough to hold being shot but not being hit against a wall. Dry dirt/dust might make a good "poof" to whatever you're shooting against, and it's free.

No, it's not cool to hit the dumpster down the road. Someone or some entity owns that dumpster. This is the kind of thing that gives spudding and youth a bad name.

Also, work on your sorry spelling and sentence structure.

What tools can you acces? Maybe you could make some kind of shot gun shell that opens on impact... Glass could be great but thats dangerous... How about you use ice? Or maybe sugar glass it would be a great thing, glass like but without the danger.
