I suppose this might be true if one is limited to factory ammo (280 rem factory ammo is pretty anemic, if you can even find it), but as a reloader I have found the opposite.
The .280 rem boasts slightly more case capacity than a .270 win, and due to the slightly larger bore the expansion ratio stays about the same.
What that means in the real world is, a .280 Rem can shoot a 140gr bullet to the same velocity as a .270 Win will a 130gr. Comparing same model bullets, we find that a 140gr .284 bullet has a better ballistic coefficient than a 130gr .277 bullet, so not only does it fly flatter, it drifts less in the wind, and hits harder when it arrives.
I had a Rem 700 MR in 280, it was a sweetheart of a rifle, regret selling that one for sure. Also played with a 280AI in a Ruger M77 and was not impressed, nice rifle for sure but the AI hassle was not worth the extra few fps that was gained. I currently have a 284 win and it shoots great, had it listed for sale but have since removed it and will work it back into my battery of rifles and keep her for the duration.
The Hagle formula for improved cartridge velocity gains is basically 25% of the percentage of case volume increase. So if you increase case volume by 10%, you will increase velocity by 2.5%, all else being equal. - dan

The Hagel formula is a pretty good rule of thumb with medium weight bullets. I have found with lighter bullets the difference seems to be less, with heavies it can be a bit more, but I digress.
For the sake of comparison, we'll use medium weight bullets.
According to Nosler, case capacities with a 150gr bullet are,
280 Rem - 62.5gr
280AI - 64.8gr.
Rounding up, that's a 4% difference.
As such, the Hagel formula predicts 1% velocity gain.

If there is one thing that Remington was good at, it was failing to market their cartridges correctly.
I think that the 280 is a nice cartridge. I was going to purchase a Dakota 10 in the 280, however the 300 H&H takes precedence in my search for a new rifle. Besides, there is no 130 gr. bullet for the 280, which I love for hunting/shooting.
I believe Barnes makes (made Maybe?) A 130 gr 7mm bullet. - dan
I have a load for the .284 cal Sierra 130 gr HPBT with RL17 from a Model 700 7mm-08. Doing slightly over 3100 fps with a 24" barrel it was extremely accurate. But the bullet looks to be discontinued now...
I think Speer makes a 130 gr .284 as well.

There's really no premium 130 gr. bullet for the .284. Nosler is all I shoot and would never shoot a HPBT or a Barnes. I enjoy the lighter, faster flat shooting bullets for my hunting environment/method. It's Nosler or nothing. If you remember, my 270 is shooting the 130 gr. accubond at 3,266 fps, and well under an inch with 5 shots. If I did purchased a 280, I would use the 140 gr. accubond. There are a few nice 280's that I have been keeping my eye on. Right now I favor the 300 H&H and will reload the 150 gr. accubond............most fast, flat and deadly accurate.

I have those Loaded in my 284 Win MR with a 22 " Barrel I need to Radar them - I'm thinking around 3200 ish ! RJ
Shoot 140's. They have the same s.d. as a 130/.277"
Could have made the 270 and /06 obsolete, with the right marketing.
I doubt that, but with proper marketing (that Remington can't seem to achieve) it could have been right up there with those two, maybe edging out the 270 given heavier bullet selection.
Pick one of the three, really not much difference.
