(Note: Mechanically these are practically identical, as are sporting Mausers in general).
The German army, which had been using the Gewehr 88, adopted on April 5, 1898 the improved form of the Mauser rifle listed as "Gewehr 98." This arm was also introduced in short length as a carbine. In 1905 these rifles were bored to give larger groove diameter for the new "S" bullet.
In 1908 a further modification was introduced which was patterned after our 1903 Springfield to combine the features of rifle and carbine. Its length was intermediate between the two earlier forms. This was officially listed as the "Kar. 98." This type was widely used by the Germans in World War I; and again with only minor modifications it served in World War II as the "Kar. 98 K," and "Kar. 98 K 42."
The original "Gewehr 98" had a heavy rear sight. When issued with a somewhat lighter rear sight, it was classed as "Gewehr 98 A." These rifles weigh 9.5 pounds, measure 49.25 inches overall, and have a barrel length of 29.15 inches. Gew. 98 was the primary World War I German rifle.
The caliber is the standard German 7.9 mm but uses a new form of pointed bullet with higher velocity and generally improved ballistics. (When originally introduced, however, this arm used the standard M. 1888 cartridge. Adoption of a pointed bullet required increasing bullet diameter and groove diameter).
It is rifled with 4-grooves of .0065 inch depth, concentric, with a twist of 1 turn in 9.39 inches, to the right. Sights are the standard barleycorn front and the leaf rear graduated from 200 to 2000 meters.
When the Spitzer (pointed) bullet was introduced the ballistic requirements of the new bullet, whidi was shorter than the round nosed, required an increase in bullet diameter from about .318 inches to about .325 inches. Representative ballistics will be found herein.
