8mm Mauser 20 Rounds Ammunition Prvi Partizan 200 Grain Full Metal Jacket

The 8X57mm Mauser (8mm Mauser, 7.92mm Mauser) was introduced by Peter Paul Mauser in 1888. Though most famous as Germany's military cartridge through both world wars it was adopted by numerous countries and its .470-inch rim and base diameter established the standard size for most non-magnum rimless cartridges to this day. The original bullet diameter, designated "J", used a .318-inch bullet. In 1904 this was changed to .323-inch, the diameter we consider "8mm" today. The larger diameter is designated "JS" or "S." With older rifles it is important to know which bullet diameter, as all American and most European factory loads use .323-inch bullets. The 8X57mm remains a popular and common hunting cartridge in Europe and is often compared to the 30-06. With less case capacity it is a bit slower, but it is typically loaded with heavier bullets and has more frontal area, so its many fans believe it hits harder. It is certainly adequate for any game that one might hunt with a 30-06. — Craig Boddington
