This is how I see it, a 270 is in an 06 case. If you have a 30-06, 25-06, 270, 280, 6.5-06, or even a 338-06, they're all the same from 0-300yds, maybe even further. I'm a .284 fan, love the caliber, love 280's, and have killed a pile of 350lb whitetail with them, as well as a pile of elk and moose with them. I've gone through my magnum phase and found that at 0-600yds they don't kill any deader than an 06 case bullet.
Animals are made of flesh and bone, an 06 case holds enough powder to drive a piece of lead deep enough through that flesh and bone to kill any North American animal out to 300yds with no problem, and if you choose the proper bullet construction, you can stretch that out a lot further.
The guy wrote the article to get a rise out of people and it obviously worked.
Despite what he wrote, everyone knows the 280ai is the king of cartridges, it just takes more time for some people to figure this out
