an interesting wildcat pistol cartridge the 224 Harvet Kay-Chuk
Back in 1940 L. Kilbourn developed the 224 Kay-Chuk cartridge from the 22 Hornet. he used the S&W Model 17 revolver chambered for the 22 long rifle. The chambers were reamed-out to chamber his 224 cartridge, which had a sharp shoulder that did not cause extraction problems, like Colt single action revolvers with Christy Gun Works 22 Hornet cylinders.
This 224 Kay-Chuk really became popular during the 1950's and considered to be one of the most effective small game cartridges and later on, still was considered superior to the S&W 22 Jet.
The 224 Kay-Chuk fired a 37 gr Sisk bullet at 1903 fps and a 40 gr Sierra at 1650 fps

.577/500 No.2 Black Powder Express
From the collection ~ .577/500 No 2 BPE paper patched.
You'll notice in the top shot of the projectile there seems to be a copper plug in there possibly to aid expansion of the projectile?
What is the consensus on that theory!
Developed as a black powder round some time before 1879 by necking down the .577 Black Powder Express to .507-inches (12.9 mm) for use in single or double rifles, as well as a variety of Martini-based lever rifles.

Winchester 22 rim fire blank in lead bullet nose 50-110 cartridge
Winchester did produce one of their 50-110 cartridge loadings using a 22 rim fire blank cartridge in the nose of the lead bullet. It was thought that this might explode the bullet but in actual hunting did not really work.
Winchester's Model 1886 lever action rifle chambered the 50-110 plus a few Winchester Hi Wall single shot rifles.
My photo shows all the cartridges factory chambered in the model 1886 Winches carbine and rifle, (45-70 missing) the 50-110 is far right and has the 22 rim fire black cartridge in the bullet noseAttachment 127497

Kynoch .577 BPE 2 3/4 inch
My .577 Black Powder Express 2 3/4 inch
The .577 BPE originated around 1870 with the 21/2-inch variant.
The 3-inch cartridge has survived to the current day as the .577 Nitro for Black, the same cartridge loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.
The 23/4-inch, 3-inch and 31/4-inch cartridges were later loaded with smokeless cordite to create the .577 Nitro Express, with the 3-inch version becoming the most popular.
These cartridges were used for the heavier species of soft skinned game, including dangerous ones such lions, tigers and wild boar. Its also useful under all but the most adverse condition against thick skinned quarries such as the gaur, cape buffalo and even elephants.

400/350 Kynoch Nitro Express
My 400/350 Kynoch with FMJRN
Introduced in 1899, the .400/350 Nitro Express is a rimmed cartridge originally designed for use in single-shot and double rifles. In 1899 Rigby approached the engineers at Mauser to make a special Gewehr 98 bolt action to handle this cartridge, its introduction in 1900 was the birth of the magnum length bolt action, paving the way for such cartridges as the .375 H&H and .416 Rigby.[3]
The .400/350 Nitro Express fires a .358" diameter 310 grain projectile at either 2000 fps or 2150 fps, depending on the source.

Kynoch .318 Westley Richards
My .318 Kynoch nitro express for the .318 Westley Richards.
Westley Richards introduced the .318, primarily for use in their M98 Mauser and later their P14 Enfield based bolt action sporting rifles.
The .318 Westley Richards is a rimless bottlenecked cartridge primarily intended for use in Africa. The bullet diameter is actually .330", the naming is due to British nomenclature which sometimes names cartridges by their land diameter rather than the more commonly applied groove diameter.
Westley Richards offered solid, soft-point or the revolutionary LT-capped[note 1] bullets in two loadings, the more common being a 250 gr bullet with a listed speed of 2,400 ft/s, whilst a lighter loading firing a 180 gr bullet at 2,700 ft/s was also offered for lighter game. The 250gr bullet possessed high sectional density and thus excellent penetration.
In my book I have on "African Rifles and Cartridges", by John "Pondoro" Taylor wrote that the 250gr .318 Westley Richards is "fully capable of driving its bullet the full length of a big elephant's body.

necking down the 375 H&H Magnum cartridge
I have fired rifles in 375 H&H over the years starting with a pre war Winchester M70 rifle and reloading and shooting my friends Ruger No 1 rifle.
But back in 1955, David Lloyd (riflemaker) in Scotland designed the 244 H&H magnum as a long range hunting rifle. He necked down the 375 H&H case to make the 244 H&H magnum cartridge which fired a 100gr bullet at 3500 fps handloading could improve the performance but the 100 gr loading has been around for a long time. Mr Lloyd also manufactured his own custom bolt action rifle for the 244 H&H cartridge.
Influenced by the 244 H&H magnum, Roy Weatherby designed his 240 Weatherby magnum, but the Weatherby 240 could never achieve the same velocity with 100 gr bullets as the 244 H&H cartridgeAttachment 127757Attachment 127758

.369 Purdey Nitro Express
Not often seen and fairly rare my .369 Nitro Express, also known as the .369 Purdey Nitro Express loaded by Kynoch, this is a centerfire, rifle cartridge developed by James Purdey & Sons and introduced in 1922.
The .369 Nitro Express is a rimmed cartridge originally designed for use in Purdey's own double rifles. The cartridge offers almost identical ballistic performance to the .375 H&H Flanged Magnum, firing a projectile of the same .375 in (9.5 mm) caliber.
As is common with cartridges for double rifles, due to the need to regulate the two barrels to the same point of aim, the .369 Nitro Express was offered in one loading, firing a 270 gr projectile at 2,525 ft/s.
In his African Rifles and Cartridges, John "Pondoro" Taylor said of the .369 Nitro Express that you "would need to go a very long way to get a better general purpose weapon"
The MkVII 303 round for scale is a MW (Munitions Welshpool) 1944 what I find interesting on this is it is roll crimped and not stab crimped as so many 303 rounds were is anyone familiar with this type of crimping.
If so how/when did they try it or was it ever going to be accepted as I have not seen much in the way of this crimp method on 303 service ammunition in my collection.

Holland & Holland Super 30 K
My Holland & Holland Super 30 Kynoch Flanged (Rimmed)
The .375 Holland & Holland Magnum proved to be so good that it took until 1925 before Holland & Holland decided that they could neck the cartridge case down to .30 caliber and produce another of the greatest hunting cartridges of all time. When it was first introduced in June 1925 Holland & Holland called it “Holland’s Super .30” and it was to become the father of a whole host of .30 caliber magnums in the succeeding decades.
Holland’s Super .30
When Holland & Holland first introduced their “Super .30” they kept it as a proprietary cartridge, so no-one else could make a rifle or ammunition in that caliber without their permission. The ammunition was loaded for Holland & Holland by British ammunition maker Kynoch. The three loadings were for a 150 grain bullet at 3.000fps, a 180 grain at 2.700fps, and a 200 grain at 2,350 fps. This performance roughly equates with the performance of the 30-06, but the flanged version (Rimmed) of the Super .30 provided flawless function in a double rifle and permitted ejectors to be used.

more 300 H&H developement
In the mid 1920's, the well known firm of Griffin & Howe of New York introduced their own cartridge, the 350 Griffin & Howe magnum. They necked down the 375 H7H to 35 cal and had Western manufacture the cartridges, sold their own custom rifles in this caliber for years.
By 1960, the US Army was looking and testing cartridges for long range sniper development and started using a modified Ackley wildcat which was called the 30 AMU. They did not use the 300 Weatherby but their 30 AMU wildcat with special headstamps by Winchester W C C 60 and Remington modified.Attachment 127787Attachment 127788Attachment 127789Attachment 127790Attachment 127791

Some Metric rounds coming.
“RWS 9.3x82 NIMROD” is c1910-1922 and is probably the commonest headstamp encountered on the 9.3x82R Nimrod.
I looked on the web but its a hard one to find the 9.3 x 74 R is there along with shorter variants of the Nimrod but of the 82mm one very little.
From the little I found its around the same as a 375 H&H but not quite as powerful you do not see to many of them.

11.15 x 65r stahl express
This is a reasonably old cartridge probably around WWI vintage 1914 +- !
The lube is gone from the projectile but all in all its not in bad shape being full lead.
The 11.15 X 65R STAHL EXPRESS was slightly less popular than the LK variation of the case length which is evidenced by its production lifespan from about 1885 until WW1.
No 1 manufactured by B Stahl indicating a St type case
No 2 manufactured by B Stahl indicating a St type case with black primer annulus
No 3 manufactured by B Stahl indicating town of manufacture with large font
No 3 manufactured by B Stahl indicating town of manufacture with large font with black primer annulus (My cartridge is of this type)
The 303 cartridge is a little unusual due to the type of crimp which is like a roll crimp instead of stab type as is typical of the service round, does anyone have a clue if they trialled different crimping styles it would be nice to know as there is bound to be some here that may have the knowledge.
I know on 303 WRA (Winchester Repeating Arms. Pic #3) primers had 4 tabs formed over the primer to stop them backing out in MG's in aircraft, well that's the story I got from a cartridge collector friend but anyway does anyone here interested in why they trialed this.
I'll look through my other 303's and see if I can find another like it and as far as I can tell it is a factory loaded round H/S MW 44 VII

small bore center fire cartridges
I do not think the Mauser Express cartridges were ever as popular as the British Express cartridges were for hunting big game. Also more difficult to locate for the collector too.
The large Mauser square bridge bolt action rifles were imported to the USA late 1920's into the 30's but expensive. The surplus Model 1917 Enfields or Model 30 Remingtons were used for large caliber custom rifles.
Small bore cartridges outside of the USA:
The 222 rimmed from Australia appeared in the 1960's, perfect for the Martini Cadet actions.
although I once rebarreled a Martini Cadet to 218 Bee which worked out. The 222R will fire a 45gr bullet at 3450 fps.
5.6x61 Vom Hofe also rimmed, introduced in Germany 1937 and re-introduced in 1962 will fire a 77 gr bullet at 3700 fps.
244 H&H uses the 375 H&H necked down introduced in 1955 in custom bolt action rifles in Scotland. will fire a 100 gr bullet at 3500 fps
5,6x57 RWS first appeared around 1964 with a 50 gr bullet at 3900 fps. Also difficult to locate cartridges in the USAAttachment 127997

7 mm cartridges & wildcats
While the 7x61 S&H was an excellent cartridge but only available in an expensive imported rifle there were so many wildcats around with inexpensive actions also available. All kinds of 7mm/30-06 and 7mm/308 including the 285 wildcat variations. Also a 240 Page made famous by Field & Stream gun editor Warren Page.

Newton Family of cartridges
Here is a photo of the Newton cartridges as detailed in my last posting.
A recent action sold a 33 Newton cartridge with the SPEER headstamp for $100.00US
Wildcat shooters still used the 30 and 35 cal Newton cartridges
Newton also designed the 22 Savage Hi power cartridge for Savage to use in their Model 99Attachment 128157
