I have had several, the 340 being one of my favorite cartridges.

The positives:

1. The stock is of good design to control recoil albeit an inch and a half short for my long neck. Weatherby uses generally very pretty lumber.
2. Their safety is one of the easiest to use in the industry.
3. The action is bank vault strong
4. They are very well put together.
5. The prices for new ones are double that of a Remchester and similar to a good Sako, but one expects to pay for quality - all in all, they are priced well considering the competitiion.

Now the down side(s):

1. Stocks frequently break at the wrist.
2. Warrantee work is tough to engage.
3. I’ve had at least two Mark V rifles where when one cycles the bolt, the bolt stop forgets about stopping the bolt and it whacks the unsuspecting user in the beak.
4. Accuracy is mediocre by today’s standards. 1 1/2” groups are about the norm (accumarks with the Kreiger button rifled barrel will shoot much tighter though). They are hunting guns, built with forend pressure. Free floating them results in shotgun patterns in my personal experience.
5. The triggers are unpredictable and the sear breaks at different times from pull to pull. Sometimes it breaks earlier than expected and sometimes later - aftermarket triggers don’t seem to remedy this situation.

I have been a long time Weatherby fanboy, but the lustre is maybe wearing off some for the buying public. I do think they are excellent hunting guns, but they really need some minor design improvements to keep up with the times. Most manufacturers strive to crowd 1/2 MoA and a lot of that is more marketing hype than reality, but the bar is being raised and maybe Weatherby should think about a few improvements to take an excellent concept into the modern age. I bought a Winchester Super Grade in .300 WSM about 2 months ago, (my very first centrefire Winchester) and I was totally blown away by the true 1/2 MoA accuracy, the excellent trigger and the overall fit and finish, all at slightly more than 1/2 the price of a Mark V deluxe. After that experience, the Weathery value proposition loses a bit of lustre.
