The coming full circle thing is a natural progression of serious hunters. Every serious hunter I know talks about it and to be honest, despite having a decade long love affair with the 300 ultra mag I can see a day when I will be using my .280 Remington exclusively. For me the ultra and any 30 cal magnum requires mucho discipline to shoot proficiently, is mentally exhausting to shoot more than a few rounds in a session and all the while devours powder and barrels.
