I run the 300 WM in order to use the 200-gn
Accubond <grin>!
I'd say it comes down to your recoil tolerance. A 300 mag is a pretty sharp kicker. If you can shoot a sharp kicker well, then it's a "better" elk rifle- it will push a heavier bullet, which is a good thing on several levels.
If recoil affects your ability to shoot well then I'd go 30-06. It is very shootable.
Let me diverge from your question even further if you don't mind. In my opinion, if you are able and willing to tolerate 300 Win Mag recoil, then buy a .338 WM instead. Many- myself included- find .338 recoil to less bothersome than 300 WM.
Anyway others with more elk experience will chime in (I've only hunted them 8-9 seasons and killed a couple), but that's my opinion.
