I am pretty sure that is the Tyrannosaurus cartridge and the range is in the emirates, I like old Billy Bob after he gets dusted and breaks the glass door, people stuff up with recoil they fight it rather than roll with it.
But I'll freely admit I was not feeling to flash after bench resting 4 rounds with that 460 Weatherby Mag.

The only thing that would be nastier than that is the 950 JDJ of which there are only 3 rifles made a totally useless weapon.

Whilst I have been yapping about Weatherby's thought I would dig out my Weatherby line up the only one missing is the 30/378 which I will get one day.
It took a while to get them all together in factory loaded trim but here they are.

The defunct cartridges like the 220 WBY Rocket and 228 WBY are missing due to being short lived and like unobtainium.

I am also missing the 30/378 from my collection, really miss the cartridge shows from years ago, they still have them but you have to travel. Just like a gun show only nothing but cartridges. years ago I bought this Newton collection, both the 33 and 40 cal Newton cartridges were made from necking up the 30 Newton, but still rare examples. Few even know about the Newton rifles and other cartridges he invented.

That 22 Newton sure has a long projectile almost looks like my 6.5 x 284's rifles cartridge.

The modern 5,6x57mm RWS is very close to the 1914 era 22 Newton (which used a shortened 30-06 case.
The 22 Newton fired a 70 gr bullet @ 3250 fps and 70 gr bullet @ 3100 fps.

Newton also designed the 22 Hi power (necked down 25-35R case) and the 250 Savage both for the Savage 99

The original 30 Newton used the 11,2x72 Schuler as a parent cartridge until WW1 started.

Also some claim there was a 270 Newton too

Here are a couple of cartridges from my collection, 2 pistol cartridges middle (Miked at 0.4485") and the right (Miked at 0.5085") are a bit intriguing both are head stamped ELEY LONDON both are C/F's with no other markings.

The cartridge on the left is an ELEY .455 Webley C/F as so head stamped used for a scale.

The one on the extreme Rt maybe/could be a Webley .476 man stopper for their 5 shot revolver the middle one I have no clues about it.

Any help would be appreciated.

Cinders, I am going to take a guess on the middle cartridge in your photo - looks like a 476 Enfield which also has a
punch mark type of crimp ?

[CINDERS]

Have not got onto the loose stuff for a bit but I picked up a full packet of these a while ago they are in good condition.
Had to rummage through the packets they had as some had reloaded ammo in them, these are all factory loaded.
Don't see these in your local gun shops around here anyways, I'll get to fossicking next week and post up some other rounds.

I think it would be correct to say that the 334 OKH developed in the 1940's by Keith, O'Neil and Hopkins by necking-up the 300 H&H to 333 diameter to use 200 to 300 gr bullets would be the grandfather to the 340 Weatherby. The 338 Winchester was developed from the 334 OKH and Weatherby took the next step with the 340 cartridge.

my photo shows the 334 OKH and the little known 350 G&H company cartridge used during the 1920's up to WW2. The third is a 458 WRA to show scale next to the 475 OKHAttachment 120029

Yes you can see how the W M morphed from the round described RCS apart from Weatherby's all being belted cartridges what sets them apart is the double radiused shoulder, on thing they do not lack and that is oomph as a factory loading they certainly get going.
The 6.5/300WM is apparently is a real barrel burner severely over bored, I know my 6.5 x 284 barrels with hot loads are usually toast at around 650-700 rounds for 1/2 MOA accuracy required.
