Nothing wrong with the marketing, it's just that bench calibers go in fads. The PPC's were a huge fad in the 80's, but newer fads have supplanted them. Bench shooters are always seeking an even Holier Grail, so new (or retreaded) cartridges with a slight change in shoulder angle, change in the size of the primer, fatter, skinnier, longer neck, shorter neck, or whatever are constantly displacing cartridges like the .222, the PPC's, the Remington BR series, and others.
