My goodness! Someone was lucky! Not quite the same but I used to have a M1 carbine. Wasn't old enough to drive yet (but could have a gun...figure that one out). We lived in a city in a fairly decent size house with an empty basement....I'm guessing you know where this is going. We had a large old moving box full of scrap wood....yes you were right this is going exactly where you thought it would. Well I closed up the house, and turned the stereo on real loud. Had a 20 round mag that I put 10 rounds in. Bang, bang, bang, bang, bang, bang. There seemed to be a lot of dust flying from behind the box on the 6th round. I moved the box........f**k there was 6 large saucer sized holes in the wall. I put the box back and never said a word to anyone. When we were packing up to move a few years later my dad saw said holes and went ballistic. He asked me what had happened. Well....It's like this I said; some of the weights that I was weightlifting with came off the bar and smacked the wall (pretty good huh?). His look said I was full of s**t but I guess it was plausible enough that the story saved my life. I told him what really happened a couple of years ago....you see...I can out run him now. Time between a teenager being a complete idiot and fessing up was about 35yrs.
