I shot a .270 until I couldn't seat a 130-grain bullet long enough to reach the rifling. Took 32 years. I have no idea of the round count, but it was my main hunting rifle most of that time. Despite the worn throat, the last three-shot group was 3/4". I sent it back to the factory for a new barrel because I was restoring the rifle to as-new condition so I could pass it down. Given how walnut and blue is no longer favored, I doubt it will ever need another.
