I here a lot of good reports on the .280. Good knock down power, good accuracy at a long distance.....But, just like the 10MM and the .40 cal handgun rounds, the .270 kinda won over the .280. I know remington discontinued the .280 in some of there line of guns, maybe the whole line. It may be hard to find that round in some gun stores (atleast in some here in MD), but I see nothing wrong with the round. Great ballistics.
