.280 Rem "experts" wanted

[Mills]

I have a .280 Rem in the works. I chose this caliber after a long study of articles, reloading manuals, ballistics charts, advice, etc. It seemed to me that it was plenty of rifle for what I needed, very practical and most importantly...not a magnum. I'm making the switch to it from a 7STW. I've scoured this site and others looking for as much .280 load data, praise, advice, etc. that I could find, but I could always use more. I was thinking about loading one bullet (the 154 grain Hornady Interbond) for everything. By everything, I mean 2 or 3 deer every year, an elk or two in my lifetime, and maybe an antelope or two. But, I've also considered going with the 139s and if an elk hunt pops up, load the 154s (or a 160 Partition) then? I live in South Dakota and in my 15 years of deer hunting my shots have ranged from 75 to 315 yards. I know there are some long time shooters of this caliber out there, and anything you can share from your experiences would be greatly appreciated.
