I have 2200 rounds through one and 300 rounds through the other. Nothing wrong with .243Win. That said, there are like 5 new entries into this "Production" category by Tikka, SIG, Winchester, Savage and Remington. I can't drop all the specs off the top of my head, but I think 2 of those can be had in .243Win. There is also a .260 in one of them.
