I don't shoot near the volume I used to, but there was a time that I'd hit that mark in ~3 years. Even at 2x that long, I'd prefer to "set it, and forget it" rather than deal with the possibility of re barreling.
My #1 gun has lasted longer than that with a .625" non-CHF barrel, but that's because there were long stretches where I was shooting various other T&E guns and it didn't get touched. I'd like to get another 10 year gun to replace it, but this time it will be "the" gun instead of "a" gun.
So, possibly yes. Having a gun that can do 20k rounds with no loss of accuracy for 10 years is appealing to me. In fact, I would say that right now it's the goal.
That said, I don't know that something like the standard ELW-F can't do that too. I'm not sure that anyone knows that.
