Step 1: materials
.2 gram bb's HAVE TO BE .2 gram!!!
2 empty Coke-Coal Or Sprite can
Gloves for your hands
Step 2: The can
Step 3: Now the tests.
Now hold the gun about one or two inches from the gun muzzle. Be shure to keep you fingers out of the line of fire. For test one you will be shooting at the round side of the can dead center. Normal where the logo is. shoot on semi once. (almost going through dosn't count!)
One side = 290-315
Now if you gun went threw those two sides you have to go to test two. For test two turn the can and look the the shiny side opposite to the top where you drink out of. Aim to the left or right of the cent (it will be marked in the picture). Again about one or two inches away on semi.
Bottom sides =350-375
Now If you BB went through the bottom side then you will need a new can. Flowing the same steps as above only now aim dead center of the bottom.
Bottom Center =400-450
Now flip you can and aim at the center (will be marked it picture) And follow the steps above.
If you can go through the top not good news for the other team. Or for you if its a aeg =p.
