The old 280 Remington is just another 'new' cartridge brought out to sell you and I yet another rifle.
The similar 7X64 is the same in Europe.
If you want a cartridge like that get a 30-06 or a 270.

"The biggest problem with the 280 is that it was introduced many hunting seasons too late. By the time it came along in 1957 the 270 and 30-06 had become America's favorite big-game cartriges and nothing else had a chance of dethroning either."
That settles it,gonna get two .280's now!
