First of all...
I can get the MK V deluxe for around 1800 and the Gold Medallion for around 1400.
You're having to pay
WAAAAAY too much for either of these rifles.
I wouldn't give a Weatherby MK-V to someone that I had a good relationship with. Sure they look pretty and nice to look at but in my experience of shooting dozens of them the performance hardly ever lives up to the price tag.
The Browning WGM is a decent enough rifle and is generally pretty accurate. If you opt for the Browning go with the X-bolt over the A-bolt. Mechanically the X-bolt is a superior rifle to the A-bolt.
Now, since you are up into the $1000 and above price range with your two considerations I would strongly recommend you look at these three rifles. All three of these rifles will come in under $2000 but I sure wouldn't shop where you have been getting prices.
