Unless you are a hand loader I'd advise skipping the .280. You really don't gain that much from the longer cartridge even in a long-barreled gun (about 140fps at the muzzle). In a short-barreled gun you'll find that the velocity is about even because the .280 doesn't handle barrel loss as well as the short-action calibers.
The biggest downfall of the .280 is ammo availabilty. 7mm-08 is pretty common in any decent sized sporting goods store whereas .280 is probably going to require mail-order.
