I have a number OF '7s - STWs, WSM and 7mm Rem mag. I've had good elk kills with all. I've found good accuracy was usually good with factory ammo. Even better accuracy with reloads. Good bullets and shot placement would make any of the sevens good elk gathers. Of course distance in my opinion favors the mag or STW.
I also have a number of thirties, the 300 WSM would however be my choice for quick short range timber hunts. Shot placement might not be in your favor and the larger frontal area of the .30 could mean a lot less tracking.
