A paintball is a small hollow sphere filled with a non-toxig, washable 'paint'. They are designed to splatter upon impact.
They are commonly available for the game of paintball, and they are round and have a fairly uniform mass - generaly good for accuracy in smoothbore barrels.
Aerodynamics
Paintballs are assumed to have a Cd of about .5, as they are smooth spheres.
They may be launched out of a curved barrel to increase range via the Magnus effect (the same at work in hop-up devices.
Use and target performance
Paintballs are typically launched out of 3/4" CPVC, as that is the most commonly available that pipe that is a close match for their diameter. Some prefer 3/4" sch 80, and the ultimate is recognized as being 3/4" sch 120, although this pipe is extremely hard to find and not commonly used. Sch 120 barrels are thicker and are a tighter fit, decreasing sag and increasing velocity.
Paintballs are typically breech loaded, and their shape allows them to be stored in magazines/clips.
Upon impact with:
- A twig, a paintball typically ruptures.
- A water-filled milk jug, a paintball typically ruptures.
- A tree, a paintball ruptures.
- A rock, a paintball ruptures.
Due to their low sectional density, most launchers will fire a paintball too fast to be considered safe, which is generally considered to be 300 fps. Furthermore, acctualy making a reliable, accurate, and rapidly firing weapon is a complicated task that probably can't be done without a lathe.
Even then, most fields won't let you play with your homebrew weapon; spudguns that fire paintballs should be considered target-practice devices only.
