Five rounds was typical... some variants of the Mauser held six... some G98 Mausers were modified during WWI to have a fixed 20 round magazine.
Need a specific model. Mauser has a very long history and continues to make firearms, not to mention the number of rifles based on the Mauser G98 action which are referred to as "Mausers", although most of them weren't made with any licensing from Mauser.
Markings on the rifle will indicate exactly when and where it was made. So- what markings are on yours?
There are various numbers, including the serial number, proofing marks, and caliber. Most Spanish Mausers were chambered in 7X57.
Soemmerda M1871 Mausers are EXTREMELY rare, and they command some impressive prices when they rarely show up.
In 1914, Mausers were made to fire a number of cartridges, and were widely exported. 7x57 and 7.92x57 were the most common, but they were also manufactured in 7.65x53 and 6.5x55.
