How To Make a (Homemade AirGun) Target Bullets

Intro : (Homemade AirGun) Target Bullets

Just recently I made a Pneumatic Pvc Airgun. It works great but, I wanted more power out of it. So I thought I should make better bullets out of something reasonably cheap. This is what I came up with.
These don't shatter easly and work very well if they are shot out of an airgun. Plus these will decompose as oposed to batteries and other metal bullets which will take a hundred or so years to. So be eco friendly and make these bullets. Please rate it if you like this instructable.
( I personally prefer batteries :) )

((((('Please rate' ))))) Out of Five thousand (Five Flipping thousand)
people only five rated my instructable.

Note: These are only done for eco friendly bullets.
These bullets might go through cardboard But these don't have enough weight
to do real damage. However I will soon post an Istructable on Way better bullets Who win in Weight, Accuracy, Distance, Durabilty and Destruction power. I'm talking about heavy weight champions.

First Step : Materials

Materials:
Hair Gel,
Pvc Piping (same size as your barrel),
Teaspoon,
Plaster of Paris,
and a bowl of water(about 3 Tablespoons)
Plus some Tape, sand paper,
Concrete ground,some tinfoil,
and a saw (possible a sharp knife)

Step 2 : Make the Plaster and Prepare The Mold

Make the Plaster
First put 3 tablespoons of water into the Bowl, then add
two tablespoons of plaster of paris. Stir it around until the plaster is disolved. add water or plaster to it make sure it will run but is still thick.

Prepare the Mold
Grap the Pvc pipe, the chopstick, and the hair gel. First scoop some gel up with the chopstick and put it in the pipe, swirl it around until the inside of the pipe is covered in gel. Now tape
the end of the pipe nicely.

Step 3 : Fill it up

Grap the plaster and start spooning it into the tube. Once it is full put it in a vice(if you don't have a vice make a base out of tin foil). now wait for about 45 minutes to a hour for it to dry.
(if you don't it will fall apart when you push it out).

Step 4 : Shaping

Push the dried plaster out of the pipe, it should come out easily if you geled it nicely. Then cut it to size with the saw 1 inch sizes are great. Now useing the concrete sharpen the ends as much as you like (you may have to sand it to fit into the barrel,

Last Step :

Now depending on wether you want bullets that are tough as nails or Bullets that shatter on the target and leave a white mark.
Shatter Bullets
Grap the bullets and leave them out to dry for about 1 to 2 days. Or if you wan't to use them right now grill them in the oven as high as it will go on the heat gauge for about 10 to 15 minutes. On the other hand you can not waste power and do what I did which was put them in the fire using a custom-made tin foil bullet holder. These are fun on targets not very good at shooting throught stuff though.

Hard Bullets
Leave them out in the sun for 15 to 20 minutes. The bullets should be quite hard but, not quite dry and your done. These work well a shooting through targets and don't shatter as easly as the Shatter Bullets.

Have fun And remeber to be safe
