Cartridges

Here is my 5.7 x 43 mm Sako think these were the .222 don't see many around these parts.

303 SMK reload for scale.

Back around 1961 the 7,62x39 was necked down to to 22 caliber, actually might have been military test before by the Soviets. Sometimes called the 5,6x39 Russians and used for competition and hunting. By 1964 SAKO had the same cartridge and called it the 220 SAKO.

the Soviet 5,6x39 fired a 43 gr bullet at 3379 fps

photo shows 5,45x39, 5,6x39 and 7,62x39

should also note that the 22PPC and 6mm PPC had the parent cartridge of theAttachment 128261 220 SAKO

Interesting information RCS thx for the share nice collection there.

My photo shows more variations to the 1950 designed 222 Remington ( I have a Rem 40XBR single shot rifle in this cal).

left the 17/222 rem wildcat which is about forty years old now, fires a 25gr bullet at 4000 fps if everything works.

next the standard 222 rem and the 222 rimmed which is not common in the USA but an excellent Martini or other single shot cartridge.

Also the 222 Rem magnum an excellent cartridge but died soon after the 223 cartridge

last the 6x47 cartridge which always had a following and still usedAttachment 128262

The 6.5 x 57 Mauser was developed @1893 - '94 as a necked down version of the 7 x 57mm cartridge. It was never adopted as a military cartridge by any military power, however it undoubtedly influenced the design of many of the 6.5 military cartridges. (Source C O W 14th Ed page 574.)

What I find interesting about this one I have is the stabs on the primer pocket which I thought was only used on some 303 rounds that I have which apparently was to stop the primers backing out when used in aircraft M.G's (see pic #2)

303 MkVII for scale.

Three auto loading cartridges from the period before and after WW1.

The first is the 9.8 Colt Auto cartridge from around 1910, designed in a slightly smaller Colt 1911 pistol. Used in trials in Romania and Serbia but never adopted. Fires a 130 gr bullet @ 1200 fps Larger diameter then 38 Colt autoAttachment 128292

the Model 1923 Thompson cartridge, 1/8 inch longer case with a 250gr bullet at 1450 fps. This was a special Thompson submachine gun design to be an improvement over the 1921 model, use a special 18 rd magazine. Soon died from lack of interest.

the 455 Webley auto issued to naval units than the flying corps. Also chambered in the Colt 1911 pistol too. Fires a 200gr bullet at 1200fps from the Webley auto pistiol, cartridges are available in USA, new manufacture

I'll load some more pics tomorrow night with Metrics no pics RCS !
It seems they come and go for me anyway don't know if any of you lose the pics failing to load up, well the top ones load and stop at #100 on my comp.

My 9.5×57mm Mannlicher–Schönauer (MS) cartridge.
This was adopted for the M-1910 MS rifle and carbine in 1910.[3] (Note: The name Schoenauer is correctly spelled Schönauer with an “umlaut” over the “o” in German.) The 9.5×57mm MS is also known as the 9.5×56mm MS, the 9.5×56.7mm MS, and the .375 Rimless Nitro Express (RNE) × 2¼ (primarily in England). The cartridge may have been created by Westley-Richards and Eley in 1908 (rather than by the Oestereichischer Waffenfabrik-Gessellschaft, Steyr (OWS) (Austrian Arms Manufacturer-Association, Steyr)), but no production rifles in this caliber have been found prior to the M-1910. This development by or on behalf of Steyr was probably an answer to the development by the noted British gunmaking firm of Holland & Holland in 1905 of their .400/375 Belted Nitro Express, designed for their specially modified Mannlicher–Schoenauer rifle (they imported the actions from Austria, but built the rifles in house). Whether the development of the 9.5×57mm Mannlicher–Schoenauer cartridge originated with OWS or with Holland's British competitor, Westley Richards certainly was the principal promoter of the new 1910 Model Mannlicher–Schoenauer rifle as evidenced by catalogs of the time. The 9.5×57mm MS is the last pre-war proprietary cartridge by Steyr and their most powerful until the recent advent of the .376 Steyr, which has its antecedents in the 9.5×57mm.

303 MkVII for scale.

Developed in Finland by necking down the military 7,62x53r cartridge to use a 6,3 mm bullet
(SAKO loading was 70gr bullet at 2936 fps) and used for long range bird hunting. They shot the birds on the ground not in flight and also used on small game.

Manufactured by Lupua and SAKO with the 6,3x53r headstamp until the early 1970's.

Russians also used their own 6,3x53r cartridge with a more powerful loadingAttachment 128347Attachment 128346

Rumbling around looking for other Metrics I found this one its not often seen and it popularity has faded with the advent of other cartridges.

My 308 Norma Magnum.
The .308 Norma Magnum (7.62×65mmBR) cartridge was created by Nils Kvale at Norma, Sweden. Like the larger .358 Norma Magnum it is based on the .300 H&H Magnum. The length of the case is the longest that would fit in a standard Mauser action. While it appeared to have a bright future initially, it was soon superseded in popularity by the .300 Winchester Magnum. The first, and one of the few, manufacturers to offer rifles in .308 Norma Magnum was Schultz & Larsen of Denmark and they still are.

In the late 1940s, Kvale designed a wildcat called 8mm Kvale. It was intended for use in the German surplus 8mm Mauser M98 that flooded the American market after the war and was therefore nicknamed 'Poor Man's Magnum'. Kvale used the case from the .300 H&H Magnum and reduced the rim diameter so it would fit the bolt of a Mauser M98. The lessons learned from this cartridge were put into the .308 and .358 Norma Magnum.

The demise of the Norma Magnum case can be summed up as a marketing failure on Norma's part. Although rifles were available in this caliber, only brass for reloading was available in large quantities, with Norma the only manufacturer of ready-made ammo. Winchester, however, was able to produce the popular model 70 rifles in their caliber and mass-produced ready-made ammo to the American public. This was the main reason of the 300 Winchester Magnum's popularity over the 308 Norma Mag. The 308 Norma Magnum is considered by many reloaders as a better caliber compared to the 300 Winchester Magnum that essentially replaced it.
