Can anyone that has this rifle tell me what you think about it, thanks

I've shot their .300 cal rifle. Once was enough, thanks.

Unless you're hunting elephant of elk from 500 yards, I see no real advantage for them. My shoulder hurts just thinking about them!

What do you want to do with it?  If you have never fired any of the smaller weatherby mags, find someone who has one (at least a .270 or better a .300 or .340) and shoot it a bit.  then ask yourself if almost twice the recoil would be nice shooting experience.  Great gun to impress the buddies at the range, but it will probably send the average shooter to the hospital for magnum eyebrow or worse.  If you are heading to some place like africa or alaska, there are other calibers that will do the job and are alot easier to  shot well.
