Looks like the OP, oneshooter, and maybe one or two other posters in that thread are pretty sound, and most of the others are a bunch of one-upping snotboxes. I don't know about .338 Lapua being 'One of the most popular sporting calibers in the world,' at least in North America it's more like 'Occasionally encountered,' and outside North America 'Sporting' calibers are not really the same thing since in the rest of the world only a small slice of quite well-to-do and connected people can indulge in hunting with large-caliber rifles.
