I found a 410 single shot leaning against a tree once. It had been there long enough the stock was gone and the barrel was bent from gravity. I put it in a bucket of oil and forgot about it. Several years later I was cleaning the barn and found it. It still won't open today. It might even be loaded. I'm sure grandad forgot it was there. This was 20 years or so after he passed. But I wouldn't throw it away. It's a neat wall hanger for the barn.
