I believe the .280 was originally designated as such.
Your right, and it's a GREAT round. I got on the 280 Rem. band wagon in the 70's and it's done all i have asked of it. I've always prefered it over the 270 Win. because of the heavier bullets available for it for "bigger", big game animials.
I've harvested caribou, blk. tail and white tail deer, blk. bears ect.. with mine, and it's always worked very well.
With handloads useing NP's, icould easily live with mine as my only big gamecartridge, for the lower 48 for the rest of my life...
