I have a 280 and its all around goodness has kept me from buying a lot of rifles in cartridges i am otherwise interested in (308, 30-06, 270). I bin cartridges in groups: under 24 caliber, 24 to 25 caliber, 26 to 28 caliber, 30 caliber, over 30 to under 375, and 375 H&H and up. I will never hunt Africa so no need for the 375H&H and up; a fast 30 with a 220 grainer will do anything the over 30 to under 375 crowd can do; ( ergo everyone needs a fast 30), the 280 fills my 26 to 28 caliber bin, my 6mm Rem fills the 24 to 25 caliber bin, and my under 24 is 5.56 NATO.
