I wouldn't be concerned about round count. It all comes down to heat and how well you look after the barrel. Don't burn it up with rapid fire or over clean it and it will outlast you. If you want "air" your testosterone (which is entirely your prerogative) then buy chromed. Experienced riflemen have ways to tell how a gun has been treated/cared for.
Think of it like a car. I'd rather buy a used car with 60k careful miles on it,—than the same model with 10k reckless miles and a few jumps thrown in for good measure—at the same price point.
