Esox is right on target.
You will never regret owning a .284 Win. It is better than the 7-08 and the .280 (though both are great).
If you want something a little more different---------look at a 6.5-284. Just size down .284 brass and go for it. My current pet loads are the 160 Partition in the .284 that is an elk thumper, and 130 TSX in the 6.5-284 that is good for about anything. Both are in long (30-06 class) actions.
