How long (as in how many rounds) does a .22 rifle really last? Many of us either have ourselves, or have father's or uncles, or grandpas, who have really old .22's that work just as well today as they did 50, 60, 80 years ago. The only thing that has me thinking, though, is how much have those rifles really been fired? When you think back to those old .22's your grandfather may have had, you don't see a 500 round brick of ammo sitting next to it. One or two 50 round boxes, was more like it. These days lots more people take their .22 out to the range or out in the woods plinking and run through 500 or 1000 rounds like it's nothing. If you take care of your stuff, how many rounds before the major stuff wears out? Wanna kill these ads? We can help!
