I finally wore out one of my bore snakes. It was a .22 caliber snake. I bought it when they first came out years ago. Every once in a while I would tie it in an old sock and run it through the washer. I noticed at the front of the brush, the snake was frayed and the snake end was sticking out. I definitely got my monies worth out of it. I had a new one in my drawer ready to replace it.
