Remington's hit and miss on marketing rounds is legendary.
IIRC, the .280 was rolled out at lower pressure compared to the .270, to accommodate their 742 semi auto rifle.
The 280 wasn't promoted at full power, at full potential while the .270 was rocking along at 60K psi.
Then it was repackaged as the 7mm Express, which as posted already, didn't work out very well. Not too unlike like the .244/6mm deal, just less successful. The 6mm package worked, is a good round. Rem just had to get the twist right.
Now, we have the .280AI, which seems to be on the right track regarding promo, loads, good brass, performance, etc.. It's just not Remington, doesn't come in a green box...
