I was looking something up in the SAAMI database and I found this: SAAMI New Cartridge & Chamber – 338 WEATHERBY REBATED PRECISION MAGNUM The drawing is dated 01/16/2022 and it was posted on 01/28/2022, just five days ago! I never heard of this cartridge. Look at the rim. It's a wide, magnum cartridge (0.5" diameter) with a 30-06 diameter rim (0.473") and a 30-06 OAL (3.380"). I bet there's going to be a lot of "standard" actions barreled, re-barreled, and re-bored for this one. It creates a whole new option for all those M98 actions out there! It will also, no doubt, become a wildcatter's dream for re-chambering all sorts of standard, 30-06 family rifles into a magnum version of the same caliber with no bolt face alteration. . | ||

Looks like they just stretched the 284 out from a 308 length to a 30-06 length. Should give a good boost to all the cartridges built on the 284 by adding the extra length. The only way to know if you can do a thing is to do it. | |||

But you don't have to open the bolt face or alter the extractor; a feat that stymies many gun cobblers. | |||

This is simply the 6.5 WBY RPM necked up to 338. The 6.5 RPM isnt setting any sales records so neck it up and see if that sells. | |||

Exactly, a simple re-barrel or re-bore and maybe a little tweaking. . | |||

Of course it won't sell any rifles, but ammo and gun companies have to invent new things in hopes of gaining sales. Ok, it will sell ten. | |||

Maybe, maybe not. It will fit nicely into Weatherby's small, 6-lug Mark V action and they may decide to offer it in the Vanguard. I'd like to see it in a Browning BLR. . | |||

or neck it up to 375 Mike Legistine actu quod scripsi? Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.  What I have learned on AR, since 2001: 1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken. 2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps. 3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges. 4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down. 5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine. 6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle. 7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions. 8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA. 9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not. 10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact. 11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores. 12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence. 13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances. | |||

What's happened to the revolutionary, indisputably better, performance-enhancing, iconic, [fill in the blank], double-radius shoulder? | |||

Convert a 9,3x62 and neck up to .366” and you have something. Same with the 35 Whelen. Interesting thing is it has the same shoulder diameter of the 9,3x66 Brenneke. A 400 RPM would be fun too. 577 BME 3"500 KILL ALL 358 GREMLIN 404-375 *we band of 45-70ers* (Founder) Single Shot Shooters Society S.S.S.S. (Founder) | |||

The 284 case is an in-between length cartridge that is longer than the 308 case and shorter than the 30.06 case. 308 case is 2.015" 284 case is 2.170" 30.06 case is 2.494" It's strange that this new Weatherby cartridge doesn't have the double radius shoulder of the original Weatherby cartridges.

The only person that I know that shoots a Weatherby is my daughter and she got that Wby Maek V 7mm Wby Mag because it is left handed, was way under priced, very pretty, has a 50 mm Leupold scope, and kills at long distances. On a Montana hunt, her guide told her that 400 yards was too far and that the open county would not allow them to get closer. She borrowed his back pack for a rest and dropped the grazing mulie buck with one shot. He was so impressed that he totted a half mile to brief me on the story. I then reminded him that she was the only hunter that passed his pre hunt accuracy test with one shot each from her .243 and her 7mm. He said, Oh, yeah, two bullseyes!

Modern Weatherby management knows that the double radius shoulder was nonsense and just 1950s marketing hype, and wisely chose to ignore it. Nothing wrong with introducing new stuff; that is called innovation. Let the market decide whether it is useful or not. | |||

Just another lame attempt to reinvent the wheel and fill some gun crank's ego to have his name on something. The problem as I see it is buy the rifle, haver fun, and in ten years try to get ammo or brass for it. Nice story by Adam Weatherby. But, I bet he could have baken his elk, moose or bear with a .30-06 or a .375. _______________________________ Cal Pappas, Willow, Alaska www.CalPappas.com www.CalPappas.blogspot.com 1994 Zimbabwe 1997 Zimbabwe 1998 Zimbabwe 1999 Zimbabwe 1999 Namibia, Botswana, Zambia--vacation 2000 Australia 2002 South Africa 2003 South Africa 2003 Zimbabwe 2005 South Africa 2005 Zimbabwe 2006 Tanzania 2006 Zimbabwe--vacation 2007 Zimbabwe--vacation 2008 Zimbabwe 2012 Australia 2013 South Africa 2013 Zimbabwe 2013 Australia 2016 Zimbabwe 2017 Zimbabwe 2018 South Africa 2018 Zimbabwe--vacation 2019 South Africa 2019 Botswana 2019 Zimbabwe vacation 2021 South Africa 2021 South Africa (2nd hunt a month later) ______________________________ | |||

Adam doesn't do those anymore on new calibers. He knows better. That and people have ballistic labs on their phones that prove it is BS. | |||

Does Norma still make Weatherby ammo? And has anyone calculated in the increase in case volume over the .338’06 A-Square or 8,5x63 Reb? Formerly Gun Barrel Ecologist | |||

iirc the rebated rim was so they could use a smaller, lighter Weatherby for the 6.5 RPM. This means the only benefit is in a Weatherby rifle unless you just like the round. 577 BME 3"500 KILL ALL 358 GREMLIN 404-375 *we band of 45-70ers* (Founder) Single Shot Shooters Society S.S.S.S.

I like the comment that Weatherby will get caught up on regular production before devoting production to the new stuff. Too many times I think companies use the shortages to force new products on consumers by only producing the new stuff. The powder companies seem the worst about this. | |||

case capacity of the 6.5 RPM was just shy of the 264 (but with a modern twist rate). So imagine this should be similar. A bit less capacity than the 338 Win, but more than the 338-06. If you think every possible niche has been filled already, thank a wildcatter! | |||

I am all for new cartridge's. I do not buy them. But they were all new at one time. | |||
