Classic Cartridges: The 7×57 Mauser

One of the world’s most useful rifle cartridges, the 7×57 Mauser, was developed by Mauser Co. of Germany in 1892. It was adopted as the Spanish military round in 1893 and soon taken up by Germany, France, and various other countries, in the ensuing years. The John Rigby Co. of England also saw its value as a sporting round and began production, calling it the .275 Rigby cartridge.

Originally, the 7×57 Mauser featured a 173 gr round-nosed, jacketed bullet that ran at about 2300fps. However, by 1913, the various military units realized that they would have a more efficient cartridge if they topped it with a 139 gr bullet at almost 2800fps.

The effectiveness of the 7×57 Mauser in the hands of the Boers caused England to redesign their .303 cartridge for more efficiency. And the US military also studied the 7×57 and used it as a model to develop the .30-06 cartridge that served us in two world wars. The 7×57 Mauser cartridge also became a favorite of sportsmen all over the world, due to its light recoil and flat trajectory. In this day and time, it is hard to believe but W.D.M. “Karamojo” Bell killed most of his 1,100 elephants with the cartridge. Bell used the 173 gr FMJ load and perfected the brain shot. The rest of us find the 7×57 Mauser to be just right for deer, the various antelope species, black bear, and elk. One of the toughest critters, pound for pound, is the aoudad sheep, yet I’ve found that they go right down when a 139gr 7×57 bullet is properly placed.

For some reason, the 7×57 Mauser has never been quite as popular with American sportsmen as it deserves to be. Only a few US companies chamber a rifle in this grand old caliber, although it is still one of the most popular calibers among those who have custom rifles built. One day, it will probably go the way of the 16 gauge shotgun and the .41 Magnum revolver. For all that, the 7×57 Mauser is truly a rifleman’s cartridge.

    My first big game rifle as a 10 year old was a 98 Mauser paratroop carbine that my dad sporterized for me in 7x57mm. I carried that rifle for so many years that I finally shot the barrel out. After that, we used the action to build a real nice .257 Roberts which is still being used to this day. I consider the 7×57 to be one of the best all round big game cartridges there is. Low recoil and kills way out of proportion to its size.

    I have one I would love to do something with but I haven’t found what I want yet. I don’t know much about mine but $100 well spent. Shoots great and it’s worn nice and smooth.

    Why not make a 7mm Mauser rifle-caliber, stripper clip fed, Saiga-pattern rifle?

    Back in the 80’s when s lot of 98 Mauser surplus came in, I was managing a large sporting goods store. 2 Czech Bruno 98’s came in. I bought them. Dad took one and had a 7×57 made and I had a 6.5×55 made. Both are superb rifles. Either will get the job done. The 7×57 has taken a lot of game, he used it a lot.
