Well, what factory chambered cartridge would you recommend to get those benefits if not a 6.5 Creedmoor? Nope the CARTRIDGE isn't MAGICAL, but as it turns out listening to the shooting community and supporting the products they want is pretty smart business. The 28 Nosler addresses some desires shooters have had, how's its popularity? What do you suppose it's popularity would be if Nosler made match grade ammo using tipped RDF bullets, a load of temp stable single base that consistently shot very well, and kept the price below $1.50ea? How about if Tikka and Kimber started chambering affordable accurate rifles to capture this market surge? Wouldn't I sound obtuse and archaic if I argued that it wasn't the cartridge but the barrel into which it's cut?
I get your point, but the fact is the same prioritization that lead to the case, lead to the twist, and lead to the loads.
