8x64 Ammo

[Roy Dassow]

Ihave found a 8X64mm round that I am not sure on. Seems to have segmented crimp and neck annealing. Totally Magnetic bullet, with no deviation in magnetism. Medium Green primer annulus with three stab crimp. Headstamp to me is typical Czech.

Apparently this information was published in the newsletter Czech cartridge of 02/1991 but we do not know more. It is an experimental sniper cartidge based on the 8x64S Brenneke (DWM 558) used for hunting in Central Europe since its design in 1912.

I have seen Belgian .22 L.R. and Waffenwerke Bruenn, Bystrica, Czechoslovakia also use this on WWII 7,92x57 so I suppose I am convinced. The web link posted that I read made me think of a Jewish connection. In fact now that I recall I have also seen it on Mexican 7,5X57 Mauser. I do not believe however I have ever seen more than a six point asterisk. Thanks for getting me thinking guys.

So you are suggesting a steeped bullet. Well the outside neck measures .350", so I suppose it could be. I am reading and article here (en.wikipedia.org/wiki/8%C3%9764mm_S) that claims there is an I or .318 version. What do you make of that suggestion?

Joe, the bullet is not stepped but just a normal spitzer bullet, the difference with the actual diameter is caused because of the seating depth and/or crimpring method used. Just as an example, you may want to try measuring an assortment of German 7,9 mm Kurz cartridges and you would obtain a bullet diameter sometimes as low as 8.04 mm (.316").

Fede, it seems I have a 8x64S Brenneke sniper loading. I measured my German 7,9 mm Kurz cartridges of which I only have around 40 and I get measurements from .321" - .316". The .316" round is a Tombak round headstamped aux - St 11 45

The famous German cartridge designer Wilhelm Brenneke put an 8x64 together in hopes of getting a military contract to build a more powerful military offering to replace the 8x57. Although unsuccessful with the contract, but owing to the popularity of the 7x57, his 1917 offering of the 7x64 (the term ""Brenneke"" is often left off the name for some reason) quickly became a hit with hunters, particularly in countries that banned the use of military rounds. Its use is widespread in Central Europe.

The designation 7x64 means a bullet diameter of 7mm (.284 inch) and a case length of 64mm. Using a 7mm bullet gives the cartridge superb ballistics as the 7mm family of bullets carry some of the highest ballistic coefficients available in their bullet weights. These bullets shoot like they are on rails! With the larger case capacity, the 7x64 is capable of pumping out lead ranging from 130 grains up to 175 grains with muzzle energies approaching 2800 foot pounds and speeds closing in on 3000 feet per second! Pretty impressive performance, right? Using the proper bullets, this dandy cartridge is suitable for almost all North American game animals.

The first was 8x64 from 1912 which was designed in a an attempt to get a government contract for a more powerful military round than the 8x57. The attempt was in vain, but as the 7x57 was already popular Brenneke also constructed the 7x64 in 1917 - 40 years before the almost identical .280 Remington was introduced. Designed solely as a hunting cartridge the 7x64 is very widespread in Central Europe as several countries here have banned the use of military calibers for hunting.
