Packing Wad Cartridge

When using the paintball cannons to launch paintballs, you must use a packing wad or cartridge that will force all the paintballs out at the same time with no loss of pressure due to "blow-by"

In a pinch, a small wad of cloth or paper towels work ok.  Plastic bags also work.   Another idea is to use foam rubber (Nerf balls, etc.), but for best results I use a homemade cartridge made from plastic cups. To make the cartridge, pick up the smallest plastic Dixie cup you can find (depending on barrel size). You will most likely have to cut them down further to make then fit in the barrel. Once you have the correct size trimmed to fit (it should be snug when placed in the barrel) then take two halves and glue the cups bottom to bottom. I use a small amount of PVC glue to glue them together.

When loading, put a wad in first, then the paintballs, then another wad to keep them from rolling out. You will have to use a stick or something to push the second wad into the barrel if it is snug like I said. If the cups are too tight, then make longitudinal cuts from the opening of the cup almost to the bottom. This will allow some give and make loading easier.

Once it is loaded, it is ready to fire.. The 2 cups will keep the paintballs in place and from rolling out of the barrel when on the field. Each wad can most likely be used several times until it is literally blown apart by the constant high pressure firing.
