I just noticed this new (?) cartridge from Weatherby and was simply wondering if anyone has any experience with it?

It's popular enough to spur Peterson to make brass for it
The 7mm STW boys will be happy, all they gotta do is neck it up to 7mm and fireform in chamber

Many people remember Roy Weatherby as the high priest of high velocity. He created new calibers that were the fastest on the market. Toward that end, he made a number of modifications to the traditional belted magnum casings of the day to achieve that goal.

300 shots and you'll be rebarreling..NOT A DAILY DRIVER BY A LONG SHOT....just too much powder for that bore

And they will have a 7x300 Wby, which has been a very popular round in some places for about 50 years.It's popular enough to spur Peterson to make brass for it

Also the cartridge that sent the 6.5x300 Wby to its early demise in the same time frame. Again, in some places.
The STW is pretty much a clone to the 7x300 Wby, and came about a few years later when the 8 mm mag case became available.
The 7mm ultra mag is at least on paper slightly superior to both.
ya, if you neck the case up to 7mm with no other changes.... but once it's fired in a 7mm STW chamber then the WBY shoulder/neck design gets blown out and it's no longer a 'Bee

Well most folks would im sure would be a bit brighter than that.
Note that i did say most. lol.
In either event 6.5 or 7x300, the 300 Wby case can get you there pretty easily.
At least it used to, before the world became much smarter.

I'm watching Graf's and soon as the 6.5-300 Wby brass is in stock I'll get 100 pcs and neck 50 pcs up to 30 cal and 50 pcs to 338 cal, hoping the necks won't thin out too much in 338, would be nice to have good brass for my 300 & 340 Wby rifles

I will be doing some load work up on some heavy Berger eol's that shouldn't hurt the barrel any worse than average. Think Berger said 2900 ish will n570. Going to try and keep it under 3000

I had one and hunted with it for a couple seasons. Shot a bull elk and a couple mule deer with it. Performance was great and my rifle was very accurate. Just dont shoot it too much , you will be rebarreling it every 600 rounds or so

Ouch. I've also read similar things about the 30-378
aka "barrel burner" Recently had a re-barrel at Sheridan & they asked me if I wanted it re-chambered in a different caliber. Without considering the possible options I said no. (.300 Weatherby). Although after 15 weeks when I received it was barreled in .300 Win mag but that was undone after a total of 5 months. (2 different calibers on the same work order)
3500 FPS with a 127gr LRX factory ammo. I'll take the short barrel life. It's not a plinker, it's loud, it kicks more than it should, and ammo is expensive. I love mine. 20-30 rounds a year gets me 15-20 years of barrel life. I'll take that.
