I track round counts very much like a car. However, primarily as indicators for when things need to be maintained, particularly changing springs. Like action springs in pistols, check wear on other parts, etc.
I don't shoot nearly at much as I used to, but it wasn't unusual for me to go through over 5000 rounds in a given gun in a year. Barrel life is a consideration for long guns, but I haven't gotten there yet. Some here shoot enough to shoot out a barrel, but I would think that the average enthusiast wouldn't have to worry about that for many years. Even decades.
