Based on lengthened 284 case.

https://weatherby.com/ammunition/6-5-wby-rpm/

Of all the whiz-bang new 6.5 mm cartridges introduced in recent years, I like this one the best.

I sure hope for Weatherby's sake someone buys it because I'm sticking with my .264 Win Mag.....

Cartridge proliferation is really not good for the firearms industry.....all it's really doing is raising the cost of shooting.

Looks very interesting. What is your opinion on it Mike?

The new range looks very good, I just wish we could get them here!

I have never been a 6.5 man but of course like many gun nuts had the 264 Winchester many years ago.

For me, I would prefer their 6.5/300 Wby and even better if they would introduce it would be a 270/300.

However, it is an interesting case. If my memory is working the 284 is .5 on the solid head and belted cases are .513, so if this is a 2.5" long case I think case capacity will be only slightly smaller than a 264 or 7 mm Rem. Maybe very close to WZM.

I can see some wildcatting with it for both necking down and up.

I am also not the biggest fan of the 6.5mm.

However, the sub 5lb rifle does make it interesting. It does make an excellent mountain rifle.

I am liking your 270-300 magnum idea. I see the agents have just brought in some Mark V accumarks in 6.5-300. Will have to wait to see if components arrive before purchasing one.

We have cartridge proliferation for ever.

One just has to look at a COW book.

Don't see how it raises the cost unless one is into buying the newest and latest.

This just proves Winchester had it right all along with he 264 Winchester Mag, the 270 Winchester, and the 284 Winchester.

I can't be there is no mention of the 26 Nosler here.

It looks like a slightly slower version of my 6.5 x 280 AI.
With 59 grains of RL-26, my 140's sail along at 3125 fps! Not bad for a projectile with a .625 BC. (your mileage may vary)

I also like that I can form brass from several sources whereas this new Weatherby case is proprietary and cannot be formed from anything. Now I'd just being too practical when I know I'm really not.

With that said, it looks like a helluva cartridge!!!

The rifle is written up in this months Outdoor Life. Decent write up. The rifle they reviewed was significantly heavier than the advertised 5 pounds. It was 6 something on the scale.

There is a steel 9 lug version of the rifle this cartridge is being introduced in as well. The rifle itself gets away from the Weatherby look. No racy lines, no hard angles, and no big Monte Carlo stock. It does have a funny webbed recoil pad.

And another round of wildcating begins. Not a lot of sense necking it down but it will likely be necked up to 284, 308 and 338 pretty quick. Maybe even 8 mm and 35 cal

Cartridge proliferation serves to increase the earned hour ratio of the manufacturing facility....this results in negative productivity and hense higher cost of production.

Further it is much less likely to be carried by many retailers forcing one to buy them on line and pay additional shipping.

This is very close to the 9.3x64 case only it has a std case head and a sharp shoulder

Was just reading a Shooting Times and it has that new Weatherby in it. Interesting there are two actions, one is made of titanium and the other normal gun steel. I bet that titanium model is expensive. They said that the titanium model can develop headspace problems. You'll have to read it.

I think the guns are $2500

Yes. It would be very easy to run a Weatherby RPM reamer into a 9.3x62 chamber and have Brenneke ballistics without messing with the bolt face. Would just have to get dies made if Weatherby didn't first come out with a 9.3...

The 9,3 could be the most logical wildcat for this case if you can make it feed from a donor 9,3x62.
9,3 Wby even has a nice ring to it.
366 RPM?
9,3 Weathnneke or Brennerby?

I like your .366 RPM idea. Sounds very American.

Interesting idea.

When Weatherby came out with a 6.5 a few years back I was hoping it would be in their existing .257, .270, 7mm case length. But in an effort to have the fastest 6.5 they based it on their longer full length .300, .340, .375 case instead . I guess it was predictable since other manufacturers have been trying to meet or exceed the speed race against them for some time. Remington's RUM, Dakota and the Nosler series of cartridges come to mind.

To me at least a shorter 6.5 that fit in the existing line would still have been better all round but it then wouldn't work in a six lug Mark V action and it would have the often misunderstood belt so out of fashion today. So it will be interesting to see how the new cartridge fares in the market place. It definitely fits into the younger generations way of thinking. We will see.

I was just going to ask about this new Weatherby round when I spotted this older thread.
I'd be tempted if they chambered it in one of the affordable Howa Vanguards.
Still feeling the call of the .257 Weatherby.

It would be a better fit if they put a longer barrel on the Vanguard package (instead of the 24"), and somehow managed to make the rifle lighter in weight overall.

I have a Vanguard in 257 Wby. It's very accurate (I did replace the factory trigger) and I do like the gun. But I personally think it's much heavier than it needs to be. Mine is a wood stocked gun, and it weighs the same as my wood stocked Win M70 in 338 WM did.

My question is always been. How far can you shoot in good conscience?
How steady can you hold your rifle and judge the wind?
Are you pinging steel plates or shooting game?
How much time do you have to make all these calculations if an animal is moving or in the brush?
Light weight rifles are not easy to hold steady and you are not shooting off a level bench in most instances in the field.
I just do not buy into the ethics of shooting game at extreme distances. Perhaps antelope on a flat prairie with a portable bench and a 14 lb rifle on a calm cool cloudy windless day without the heat waves.
For a long time we have had cartridges like a 270 Weatherby that will approach 3500 FPS with a 130 gr. bullet. Sight it in 2.5" high at 100 yds and a 400 yd. shot is legitimate without all the scope compensations and dials and other lines in your sight picture, heart pounding from excitement or physical exertion.
Food for thought...Make it simple.
Might try and get closer.
