The 280 is well suited for both deer and elk, unlike the 270 where elk/black bearbullets are hard to get hold of. 280 generally will take more variation in the loads and give fairlyconsistent accuracy with all; I don't know if some get a lucky 270 that shoots 'em all but usually they are more picky. Advantages of the 270 are easy to find factory ammo, and cheaper ammo at that. It's easier to get the rifle you want in this caliber. It recoils less, but not by much. If it were my choice I'd go for the 280
