Penetration testing photos thread

[shockwave]

Ok, this is meant to be a thread where ppl can post photos of things they shot with their cannons. I'm particulary thinking of coins as a testing material and guns that shoot small projectiles. You can post photos of a coin shot with your favorite commertial airgun even real gun. That way we can all compare eachothers results. You should allso supply as much info about the test as possible. Here are my results.
