Well I'd avoid the weatherby calibers just because both factory ammo and brass are going to be much higher than with standard calibers.
What is your maximum range?
I'd always go for the heavier 7mm due to better ballistic coefficient in a magnum if you're reaching beyond 750yds.
If not, I'd look to something along the lines of the .260 Rem, .6.5 Rem Mag, or 6.5x284.
Of course I shoot bobcats and coyotes with a 7mm STW and just bought a 300 RUM, but for an everyday plinker/varmint/deer rifle I built an AR LR-260.
I'm comfortable with all of the above out to 1000yds on coyotes and smaller game but limit myself to the 7mm STW and 300Rum for the big stuff at those ranges.
I wouldn't hesitate for a second or think twice though about any of the .264/6.5's for even elk at 750 or less.
Largely what your limits are, will be set by your own skill and confidence levels.
