New Weatherby Cartridge!

Any concrete data on barrel life? Unless those barrels are cold-forged of unobtainium quenched in hardon gas, can't see that being very long. Also, any published ballistics?
 
I guess WBY has seen the writing on the wall and decided to step up it's game. WBY brought velocity and the concept of "high quality" to the game decades ago, but I'm sure they have seen their market share plummet in recent years. WBY had always appealed to the high end market, but these days people that want good stuff have way more options and want precision.

"Double radius shoulders" and "freebore" are so old school that few will still fall for that nonsense anymore.

WBY has painted themselves into a trap. WBY style cartridges are not in favor anymore, and for good reason. I doubt this cartridge will catch fire. It ain't no 300WSM or 375 Ruger ;)

I expect with the Vanguard line of good quality - working man priced rifles, the availability of non Weatherby chamberings in Weatherby rifles, and the availability of affordable brass for some Weatherby cartridges from other manufacturers, Weatherby's market share is greater than its ever been. While its true that there is a great selection of high end rifles available to the consumer, there are those who are doggedly brand loyal to Weatherby. While propriety cartridges will never be as popular as standard cartridges, I don't see the Weatherby's line of cartridges disappearing any time soon. Weatherby has been around since the '40s, but what has become of Lazzaroni? So I'm not sure what trap you might be referring to, other than Weatherby carving out their own niche in a tough and competitive market place.

As for the comparison of Weatherby cartridges to the .300 WSM or the .375 Ruger; the .375 Ruger makes sense to me, when its chambered in the Alaskan rifle. The .375 Ruger provides adequate power, from a compact rifle, while producing modest recoil, and its at its best when loaded with light to mid weight bullets. There is nothing in the market place that is better in the role of a dangerous bear rifle, for use in thick cover. But the .378 Weatherby is more versatile, is better suited to African and Asiatic dangerous game, and outperforms the Ruger by a significant margin, to the extent that it will do anything the .375 Ruger will do, even when throttled back to 85% of it's potential.

Personally, I see little point in the .300 WSM in the context of .300 magnum rifles. That is not to say its not a good cartridge; IMHO, it fills a valuable niche, but it should not be viewed in the same light as a .300 magnum. The man who wants .300 magnum performance is better served with a long cartridge like the .308 Norma, .300 Winchester or the .300 Weatherby. Long bullets like mono-metals or Berger's popular Hunting VLDs, must be seated out so far in the .300 WSM, so as not to interfere with the short powder column, that it would have to be used in a long action rifle, and if it's velocity potential is realized, the barrel needs to be as long as the full sized .300 magnum's. Even when the .300 WSM's velocity potential is realized, it lags signicantly behind the .300 Weatherby. If the .300 WSM is chambered in a compact hunting rifle, which was the point of it's design, its comes closer to .30/06 performance . . . which isn't bad, but its no .300 magnum. Therefore the .300 WSM's niche is better directed to the hunter who might be considering a .300 Savage or .308 Winchester but wants just a bit more, from his compact rifle, either for hunting larger species of game, or just for a flatter trajectory. Viewed in this light, the .300 WSM is an intelligent choice, but I believe it would be a mistake for the rifleman who wants .300 magnum performance to choose it.

Will the 6.5-300 Weatherby be a commercial success? The interest in high velocity small bore cartridges is certainly there, and the American market place appears to have finally opened it's heart to the advantages of the 6.5 bore. The 6.5-300 Weatherby wildcat has been with us since the late '60s, so I have no doubt that it's legitimized form will be with us for some time to come.

So overbore that it is going to eat throats like chocolate. I get it though, it is a cool cartridge with wicked ballistics; and it is not like someone is going to take it out to a pasture full of gophers.
 
Boomer, this is exactly the response you must expect from some one whose every rifle is built on something based on the 308 case.........with the attention span of a gnat...........C'mon Hoyt, drink the Kool-Aid, think hyper velocity 6.5s.............drink the Kool-Aid, think hyper velocity 6.5s, drink the Kool-Aid...............................Ah hell, I won't be building one any time soon either............could have had one years ago, but I'm not much of a deer hunter, and where I hunt sheep and goats I much prefer a 300 Mag for it's potential with other residents...........so I have no need for anything faster than my 264 WM, or even the 264 for that matter. With my 257 Wby fulfilling my hyper drive needs and more than adequate for long range deer hurting, then on up to my 7mm RUM, carrying hyper drive to a heavier level, I have no need for an in between hyper drive....................If the 257 Wby is too light for the game I intend to hunt, I ain't pulling out a 6.5, I'm blowing past 6.5 to at least 7mm and likely even 30cal.............with a 340 in the wings just in case.........
 
Never owned a weatherby cartridge myself. Looking at average case capacity of weatherby calibers, I can only assume they consume a pound of powder very quickly. Is it worth it?

They can dam near shoot out into space, but in order to do that ( shoot out into space ) you will need a solar Powered Lazer Beam Guitar.
Wby Cartridges do eat a lot of powder, but as does a the Audi A8 needs lots of Premium Fuel to go fast.
Haters are gonna hate and those that wanna be different are going to go WSM , Win Mag or even along the lines of the Ruger cartridges.
The trade offs are many as are opinions on which is better and why.
 
Looks like the new Mark V's will all be guaranteed sub MOA according to www. americanhunter.org/articles/2015/9/29/weatherby-introduces-the-new-mark-v-rifle

Then why are the R.C. models still listed?

Just received the Canadian Direct Dealer pricing/product list from Weatherby this morning. The 6.5/300 wby will be available in the Arroyo, Arroyo RC, Outfitter, Outfitter RC, Terramark, Terramark RC, Accumark, Accumark RC, Ultra Lightweight,

If all Mark fives get the moa guarantee, there would be no point to the R.C. models.
 
Boomer the 375 Ruger and 300WSM reference was about new cartridges. There have been several new cartridges released in the last couple of decades, some have been successful, some have flopped. these 2 are successful examples. I don't see The 6.5 WBY as one of these.

People that want a fast moving 6.5 now have 2 new cartridges with virtually identical velocities. I just don't see the type that want a fast 6.5 choosing a WBY. I'm sure they will sell to some hardcore WBY fans that still get excited about double radius shoulders though.
 
I'm with you MIG.......at 4 bucks a pop for 26 Nosler brass, as opposed to 10 different options with which to make 6.5 X 300 Wby brass for less than a buck a pop, I don't see a bright future for the Nosler offering.
 
Given the performance comparison I wonder how the purchase price of the respective rifles would compare.
Not that I am going to run out and buy one..... just curious...


If they do it in the S2 they will sell like hotcakes and the Nosler sales will drop off.
 
Boomer, this is exactly the response you must expect from some one whose every rifle is built on something based on the 308 case.........with the attention span of a gnat...........C'mon Hoyt, drink the Kool-Aid, think hyper velocity.

Not quite... but not far off. I have builds on the .308 case, .30/06 case, X57 case, even WM case.... however, unlike you Northwestern dudes, I have little need of more than the 08 case... and all of my 6.5 experience has been timid in the .260, 6.5 CR, 6.5X55 range... and I some time ago bailed on the 6.5's altogether...

No Kool-aid here... more of a Tang guy... less "Jonestown."

If all Mark fives get the moa guarantee, there would be no point to the R.C. models.

I don't have a good answer to why are they still listed, I would think it's because the RC's offer more than just the accuracy guarantee? I'm going to trust Weatherby's website (ww w.weatherby.com/products/rifles/mark-v.html) it says "The New Mark V® rifles all come with our SUB-MOA accuracy guarantee."

If you look at their site I think the "advantage" to the RC is that it comes with load data for the sub moa load, a fancy floorplate that tells people its range certified and a piece of paper which bears Ed or Adam Weatherby's signature.... but the Mark V's both have a sub MOA guarantee.
