I have put over 5000 through mine this year already. My dads old bone stock one has no number but, it was bought in 1987 and we shot it my whole life. Many, many bricks some of the years too. And, it saw little to no cleaning for many of those thousands of rounds. I used to shoot pennies at 100 yards, when I was a little kid, with that thing bone stock with a cheap Banner 4x. I think we all can agree, the old 10-22 is one of the best rifles ever produced.
