I just got one a few months ago, but have only had it out to my range for one session. It's pictured on top. Lower gun is a 338-378.
If you plan to hand load for it, you need to get some US 869 powder.

Shot a few three shot groups at 100 with it.
I'm not sure what the issue is with the Weatherby Factory (Hornady bullet) ammo, but my rifle doesn't shoot it very well at all.

Weatherby Factory 140gr Hornady, Group 1 - 2.5"
140gr Accubond 1.1"
143gr ELD-X 7/16"
130gr Berger Hunter 1-3/8"
140gr Partition 15/16"
Weatherby Factory 130gr Scirroco 1.1"
Weatherby Factory 140gr Hornady, Group 2 - 3.1"
120gr TTSX 3/4"

Run it up, until you blow it up, then back it down a bit.
