True...I'm a fan and user of the .280 Rem, .257 Bob, .250 Savage, .30-30, and have used the .303 Savage and the .351 Winchester, but it would be folly to ignore the advantages of a few of the newer rounds. Myself, I prefer moderate recoil and range, so the two newer ones that attract me most are the .260 Remington, which I think would be a more practical cartridge than my beloved .257 Bob, and the .338 Federal, which offers a bit more bullet weight than its .308 Win parent round. Unfortunately I think WAY too many people compare it to the .358 Winchester and in the opinion of most of these nay-sayers it comes up short. I hope more people go out and buy the rifles now that Tikka's cataloguing them; I expect Browning to follow suit soon if they haven't already. Maybe the Federal round won't be ignored to death like the excellent .358 was. The .260 seems to be gaining a following after a bumpy start. Even Sako is cataloguing it now!
I have no need for the WHOP! factor of the short mags but I must say it's about time the ammo companies caught on to the idea of non-belted mags, and if I wanted a bit more oomph than my .280 gives me, I'd look seriously at a .300 short mag.
Seriously though, with a few exceptions, I think most of the shooters who post here share your opinion about the new developments. Where we seem to diverge is on their necessity! (LOL)
