I reload and shoot the following 7mm calibers:
7mm Rem Mag
.280 Rem
7 x 57 mauser
7-08 Rem ackley improved
7-08 Remington
7 mm Benchrest
I guess you can say I'm fond of this class of bullets.
All of the calibers above will work fine in the situation you mention. I would pick one that works well with the style of gun you wish to shoot. That is Long Barrel, Short Barrel, Carbine Length, Long action, Short action, Heavy contour, Lightweight contour, Mountain rifle, etc, etc.
In summary, I think you will be the most happy choosing a style of gun you like and enjoy shooting. Let that dictate the caliber you choose.
My 2 cents
