7.92mm & 8x57

GIFFROY · 10-11-2011, 03:10 PM

8x57 J (J=I= Infantry) is the first 8 mm German Army Rifle caliber made for Black powder; his caliber is .318.
8x57 JS (J= Infantry; S = spitz/pointed) is the second 8 mm German caliber made for smokeless powder ; his caliber is .323. When changing the powder they changed also the shape of the bullet who became pointed.
It must be mentionned that the (very common) ammunition 8x57JS or 8mm Mauser will chamber in rifles made in .318. Such thing will make overpressures.
