ive seen this done live by a bubba neighbor of mine at camp.... (bubba = guys who do less than brilliant things with firearms)
he used some type of washer, not dimes. he ran 5 rounds and dropped a pretty thick tree so i guess they worked, but at same time i would not consider these viable inside a structure
