Though I am something of a fan of the 6.5 Creedmoor, I was, of course, being sarcastic. It is a good little round for a lot of reasons and might just be the perfect white tail cartridge (with jacketed bullet, anyway). I like the platform mine is in, Ruger American Predator. I just knew it would stir the pot in this crowd.
Nothing wrong with the cartridge, as had been proven over and over for more than a hundred years.
"Same Great Product - All New Packaging!"
The hype though, and the way the Kool-Aide crowd sucks it up...
In real terms though, mere musing takes a back seat to real losses - like readily available brass for millions of existing guns and discontinued, long, heavy, cheap cup-n-core bullets, displaced artificially, by expensive, lighter (hey, where'd all that legendary sectional density go?) boutique bullets, not by actual demand, but by halting production on the existing stuff to make room on the shelves for the new stuff. The horse gets ahead of the cart and the old stuff doesn't go away not because the new stuff is found to be so much better - it goes away because it's TAKEN away. Old Adam Smith's "Invisible Hand" has been hand-cuffed to a bike rack somewhere.
Some fashion genius announces that "next year, everyone will be wearing jeans with more holes than fabric!"
Then, it HAPPENS and people wonder HOW he KNEW THAT!!
Self-fulfilling prophecy.
Not really much wrong with most of the "new" cartridges I've seen in my lifetime, but very, very few are so much better than what we already had. If they ARE that much better, very very few people could actually see the difference with mediocre shooting from production guns.
It's not the cartridges which are in question, rather the hype around tiny advances which may or may not be worth making.
