It is known as. It was developed by Paul Mauser of the Mauser company in and adopted as a military cartridge by Spain in Many sporting rifles in this calibre were made by British riflemakers, among whom John Rigby was prominent; and, catering for the British preference for calibres to be designated in inches, Rigby called this chambering the.
Like the 7. The Mauser Model rifle turned out to be a transitional design that was manufactured in limited numbers for the Spanish Army. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, under extreme conditions.
According to the official C.The Big Daddy of All ~ The 7x57mm Mauser!
A rimmed cartridge greatly simplifies the issues of designing an extractor, particularly in a combination gun or "drilling" which must also be designed to extract rimmed shotgun shells.
While various modern break-action and single-shot rifle and pistol designs have been developed that can reliably extract rimless cartridges, most of these date from the s or later.
In particular, the cartridge web, the area immediately above the rim on the rimmed version or the rebate on the rimless version, is thinner in the rimmed case, and some authorities recommend limiting the rimmed cartridge to 41, CUP because of this. All sizes in millimeters mm. The relatively flat trajectory and manageable recoil ensured its place as a sportsman's cartridge.
This made it popular in Africa, where it was used on animals up to and including elephants, for which it was particularly favoured by noted ivory hunter W. Bell sectioned an elephant skull to determine the size and location of the brain, and used careful aim to ensure bullet placement in the brain. Corbett's writings mention using the.
For man-eating tigers, Corbett preferred a double-barrelled. This is well known to hunters, through both personal experience and the reading of a well-documented track record extending back more than years. The military of the Kingdom of Spain adopted the Mauser Model rifle. The original cartridge featured a long, At the same time, it exhibited relatively modest free recoil.
That was a combination of attributes that made it popular with both soldiers and sportsmen alike. At the commencement of the American assault on the strategic Cuban city of SantiagoSpanish troops defended positions on San Juan and Kettle Hills. Though the assault was successful, the Americans soon realized that they had suffered more than 1, casualties, nearly 20 per cent of their forces. The oldest pattern military ball ammunition was loaded with a Cartridge Type: Rifle Height: 2.
The case is an original design with a rimless, bottleneck type case that fits a. It has a large rifle primer with a The ballistic performance for the 7. The 7x57 Mauser has become a popular hunting rifle for shooters, and has been used by militaries such as the Spanish government.
The 7x57 Mauser has a almost flat trajectory along with a moderate recoil when fired. In addition it has good wound penetration on game up to the size of an elephant, which has been noted by such hunters as Walter Bell. Bell was famous for his African Safari hunting expeditions during the early 's, but later caliber rounds have replaced big game hunting cartridges such as the 7x57 Mauser.
Now it used on game in North America up to the size of moose in most cases. While we have went to great lengths to make sure that it's as accurate as possible this rendering should not be used to generate specs for casings. The PowerRank is an estimation of the cartridge power.
The first number is the value of this cartridge, and the last number is the value of the most powerful round in our bullet database.

Random Guns Gallery.Usually, this column looks at recent innovations related to today's military rifles and ammunition, but this issue I'm taking a look back. Sort of. I decided to examine what happens when you take a classic 19th century military rifle cartridge—specifically the 7x57 Mauser—and update it using the latest modern projectiles currently available for handloading.
Few pre-World War I cartridges will have their exterior ballistics dramatically improved simply by topping them with a modern bullet—although accuracy and terminal performance often will be. The famous vintage 7x57 Mauser is one cartridge that can really benefit from load development with today's components and powders.
Unlike most military rifle cartridges, Paul Mauser's 7x57 quickly earned an impressive reputation among soldiers and sportsmen alike. At the time, it was known for its accuracy, flat trajectory, mild recoil and impressive performance on game animals well beyond what its paper ballistics would lead you to believe. It decisively trounced the U. Today, though, the 7x57's original 2,fps grain roundnose ball round seems worthy of little more than scorn.
What happens, though, if we drop the 7x57 into a modern rifle and top it with contemporary high ballistic coefficient projectiles? Will we see a truly dramatic improvement in its exterior ballistics? Will the improvement be enough to allow it run with the current "big dogs" popular with American riflemen? Good questions. A quick perusal of three popular bullet manufacturers—Berger Bullets, Hornady and Sierra—reveals a host of interesting possibilities.
All three manufacturers offer high BC projectiles in bullet weights suitable for use in the 7x While some, such as Berger's grain EOL Elite Hunter, may initially appear a bit on the heavy side, it handles them surprisingly well. Considering BCs starting in the high. The 7x57 Mauser has a case length of 2. Shoulder angle is Case capacity is 60 grains of water. A variety of powders readily available to handloaders perform quite well in the 7x Of these, I am particularly fond of RL and used it in testing because its slow burn rate works well with heavy bullets, and I found it capable both of high velocities and excellent accuracy.
I used Winchester standard Large Rifle primers and Norma cases. Cartridge OAL was 3. For testing I selected a factory Ruger Model 77 African with a inch barrel.The 7mm Mauser — also known as the 7x57mm Mauser, 7mm Spanish Mauser and.
Armies found the round was accurate at long range with moderate recoil. Hunters discovered the round offered good killing power with deep penetration and minimal recoil in lightweight rifles. Sure, the 7mm Mauser is an old-timer, but this older round can keep up with newer ones. But as has been demonstrated, the round has been used quite effectively on the biggest game animals — elephants. For handloaders, manufacturers make a wide variety of excellent 7mm bullets, allowing it to be loaded with bullets weights from to grains.
The 7x57mm Mauser was a game changer in military and hunting cartridges. It was brutally clear that Spanish forces were better equipped than American soldiers. More than 15, U. San Juan heights protected the city.
In the tropical heat on July 1, American troops attacked. About U. Spanish losses were minimal considering the size of the attacking American force. About soldiers were killed and wounded. Not only was the Mauser quicker to reload via a stripper clip, but the 7x57mm cartridge had a farther effective range and was more accurate. The U. Model Krag-Jorgenson rifle was no match. The slow-loading Krag rifle and its caliber.
The rifle was a modified Mauser rifle called the M Springfield, chambered in. The 7mm Spanish Mauser really pushed U. Other European and Latin-American countries — Brazil, Uruguay, Colombia and others — also adopted the cartridge and rifle for military use.
It was a turning point in modern cartridge design. The 7x57mm was cutting edge at the time and used new in the late 19th century smokeless powder. The original military bullet was a round-nose, grain full-metal jacket.
The case measured 57 millimeters long, which is why the cartridge is also called the 7x57mm. At the time, those ballistics were impressive.
The round was also fairly flat shooting, and offered excellent penetration and modest felt recoil. Part of the success of the cartridge was the long, heavy bullets used. They have a high sectional density. Bullets of the same shape but with more weight in relation to their diameter retain their velocity and energy better.
The 7x57mmR is like the 7x57mm Mauser. Suffice to say, the 7x57mmR is rare today and is mainly encountered in European break-action guns. The British were armed with the.History shows that once a new factory cartridge of the same calibre with improved ballistics has been introduced, the skids are greased under the old one which will begin a steady slide in the oldsters popularity and eventually, into obscurity.
A good example of this is what happened to the 7x57mm Mauser when the 7mm appeared in Factory loads for the 7x57 were being loaded to moderate chamber pressures to drive a gn bullet at fps in deference to all the old rifles still in use. Then suddenly in the 7mm appeared on the scene, lofting out a gn bullet at fps.
Being based on the. The 7mm was developed for metallic silhouette shooting and according to tests carried out by Remington, at yards it showed an edge of fps and lbs of energy over the. So, the 7mm drove the last nail in the coffin of the 7x57 which had been barely hanging on by the skin of its teeth. In factory ammo at least, then, the 7mm is faster and flatter shooting. It fits modern concepts of what a hunting cartridge should be better than does the 7x Ideally chambered in lightweight, short action rifles, the 7mm combined mild recoil and superb accuracy with adequate killing power for medium-size game.
Early summations that the 7mm could be loaded with bullets heavier than grains making it suitable for heavier game such as wapiti may have fired up the hoi polloi, but I was unconvinced and still am. Above: The 7x57 really comes into its own with handloads. B ullet choices include: Speer gn H. History is uncertain of the date of origin of the 7x57 cartridge. The 7. Then, inPaul Mauser visited Spain, taking with him a new rifle and cartridge of his own design. Apparently this was the round that later became known as the 7mm Mauser.
The 7mm bullet had a flatter trajectory than its contemporaries because of greater muzzle velocity, which was a definite advantage in the eyes of the military. The superiority of the 7mm was probably due its being loaded with the then new smokeless powder which was at that stage of its development making great improvements in propellants. Physically, the cartridge was something of a composite of earlier Mauser cartridges since it had the case length of the German-type of and the shoulder position of the 7.
Ballistics gave a The rifle was very similar to the Spanish Model of which had the magazine extending below the stock because the cartridges were held in a single column.
For mounted troops, there was a carbine of the same style. The 7mm Mauser cartridge was adopted prior to the Modelwhich appeared late in and was the first military rifle to use a staggered magazine contained in the stock. It copied the British Lee types, but because the 7mm was a rimless round, the magazine posed fewer problems. Eleven countries, several in South America have used the 7mm Mauser as their military round, in both rifles and machineguns.
In the U. S, Remington chambered the famous rolling-block military rifle as well as the Lee bolt-action for the 7mm Mauser.
Bore and groove diameters were standardised at. Later Ruger rifles have a Very few rifles are being chambered for the 7x57 today, but they include the CZDakota 76 and Ruger International, while several European makers like Voere, Krieghoff and Merkel still list it.
This is one of the best-balanced cartridges ever designed. It has proven to be fine for all-around hunting with a fairly flat trajectory, moderate recoil and a wide selection of bullet weights, with sufficient energy to cleanly kill most species. In England it was called the. In Europe, the 7x57 is still a popular choice for all-round use. It does not destroy a lot of meat on smaller animals, such as roe deer, yet is powerful enough for use on larger species.
With the proper bullet, careful shot placement and a hunter who is willing to pass up shots at too great a range it is adequate for most American game, although some experts would consider it to be on the light side for wapiti, moose and bears.
Bell used it with FMJ bullets to take several hundred African elephants as well as thousands of head of plains game. This is better for handloaders than the relatively short 7.It gained fame on the losing sides in the Spanish-American and second Boer wars, where both rifle and cartridge proved superior to the.
This persuaded the US to develop the M Springfield and a rimless. The British were slower on the uptake, but did have a somewhat more powerful cartridge called the. The British, however, called it the. The original military load used a full-metal-jacket roundnosed bullet of to grains at approximately 2, feet per second, providing plenty of penetration on both enemy soldiers and elephant skulls.
But after the almost universal military switch to lighter pointed bullets at higher velocities during the early 20th century, most countries used a grain spitzer at about 2, to 2, fps. Softpoint hunting ammunition is still primarily loaded with minor variations on those two bullets.
Mine have taken pronghorn and springbok the African equivalent of pronghorn at ranges out to yards. Instead its problems revolve around variations in action strength and chamber dimensions. This results in widely varying pressures with the same powder charges and bullets, and sometimes in accuracy troubles.
A few rifles with very long throats have refused to shoot accurately with bullets weighing less than grains, due to the long jump shorter bullets have to make before they hit the lands. With appropriate powders, velocity correlates strongly with pressure. But the powder charge required to reach those levels varies considerably from rifle to rifle.
As an example, with IMR or H and grain bullets, the charge required to reach 2, fps can vary up to 3 grains, even in barrels of equal length. If you take a look at the latest data, however, many times IMR turns out to be slightly slower when loaded with the same bullet in the same cartridge.
Good luck, since it also varies around 3 grains with grain bullets. Light-to-medium weight bullets at higher velocity seem to do the job quicker, while penetrating plenty.
Two favorites are the grain Nosler Partition and Norma Oryx. Both expand easily on deer-sized game, yet penetrate sufficiently on larger game, and do more interior damage than heavier premiums at slower velocities. John has taken moose above and kudu below with his Kilimanjaro rifle.

As with several early smokeless military rounds, this relatively fast twist inadvertently made the 7x57 very versatile because it could handle a wide range of bullet weights and styles, including lighter, faster and more streamlined bullets.
Quite a few, however, regarded it as more suitable for those unfortunate humans who somehow could not tolerate the recoil of a. In it we have a choice of either a grain bullet at feet velocity or a grain bullet at feet velocity. With it the biggest game on the American Continent has been killed. Curtis has used it on several expeditions with complete satisfaction.
For the man who is. Eventually enough hunters liked the 7x57 that, as handloading became more popular, they realized other bullets could make it even more versatile. Philip B. After World War II, when firearms factories started making hunting rifles again, the 7x57 failed to reappear. However, this changed over the next few decades, partly due to Ruger offering it as standard in both the Model 77 bolt action and No.
The 7mm solved one new problem of manufacturing modern 7x57 hunting rifles, along with an old problem. This worked fine with heavier bullets, but accuracy could be iffy with lighter bullets. During the same period, nonhandloading hunters became obsessed with velocity, due to the magnum mania that began after the war. The longest throats were in the old Mauser military rifles and a Ruger No. The throat-length difference between the Serengeti and the red-pad Ruger No.
Both my second Ruger No. These widely varying throat lengths resulted in widely varying pressures, another reason American 7x57 ammunition tends to be pretty mild.
This also complicates loading data, one reason published 7x57 powder charges vary considerably from manual to manual. Due to differences in throat length, both kinds of loads produce considerably different velocities in inch barrels. In that rifle, My next 7x57 was the long-throated Ruger 1A, also with a inch barrel, which provided 2, fps with the same load, and required Since then a few other 7x57s with or inch barrels have provided 2, fps with only Knowing this does not solve the problem of widely varying loading data, the reason that for years I loaded 7x57s largely by muzzle velocity.
With the few sources showing modern rifle-pressure data, top muzzle velocities from to inch barrels are around 3, fps for grain bullets, 2, for s, 2, for s, 2, for s and 2, for s. When muzzle velocities approached those levels, I stopped adding powder, and my handloads never resulted in the slightest sign of high pressure, even in more than 90 degree Fahrenheit August temperatures, whether during southwestern pronghorn seasons or safaris in southern Africa.
However, a couple of years ago it occurred to me that the velocities of modern 7x57 data resembled 7mm Remington data. I reasoned that using 7mm data as a starting point would be safe in modern 7x57s, because the slightly larger 7x57 case would result in lower pressure, even in a short-throated rifle.
However, their extensive 7mm data includes far more powders, including Big Game and Hunter, so I tried the loads in the Serengeti with excellent results.
Newer 7mm bullets have also appeared, often with higher ballistic coefficients BC. While many, if not most, handloaders associate high BC with high muzzle velocity, high-BC bullets tend to help considerably, even in moderate-velocity rounds.
First, the impact velocity at close range is kinder to cup-and-core bullets, allowing them to expand and penetrate well, and at longer ranges the higher retained velocity helps insure expansion.
