Simple Experiment...........

Take a HEAVY duty can.................put it inside another can...........GARBAGE cans work GREAT.

Put a hot plate under the smaller can.............and throw a couple 22 rounds into the smaller can........Once the smaller can heats up enough the 22 rounds will "pop".

AND there is enough ENERGY to go completely through the smaller can,and put a SERIOUS dent in the outer can.

DID this as a kid too................
