The bullet is unimportant, it is the shock wave created that causes the stuff to dislodge, like another poster said hydrofraking. Seem like I came across something several years ago that the average bullet will only penatrate about 3 feet of water. You could create the same effect with a blank cartridge.Does the shock of the bullet striking the water dislodge the iron or does the bullet hitting the screen clear it or punch a hole in it?
For the other poster about the shock wave. some gets absorbed into the ground, and surrounding area, but most gets transfered back out the top of the open well
