DWM Mauser Model1898-B/A Rifle- 7×57 cal
he Gewehr 98 (abbreviated G98, Gew 98 or M98) is a German bolt action rifle made by Mauser firing cartridges from a 5-round internal clip-loaded magazine. It was the German service rifle from 1898 to 1935, when it was replaced by the Karabiner 98k, a shorter weapon using the same basic design. The Gewehr 98 action, using a stripper clip loaded with the 7.92×57mm Mauser cartridge, successfully combined and improved several bolt action engineering concepts which were soon adopted by many other countries including the UK, Japan, and the US. The Gewehr 98 replaced the earlier Gewehr 1888 rifle as the main German service rifle and first saw combat in the Chinese Boxer Rebellion and was the main German infantry service rifle of World War I. The Gewehr 98 saw further military use by the Ottoman Empire and Nationalist Spain.
The 7×57mm cartridge, also known as the 7mm Mauser, 7×57mm Mauser, 7mm Spanish Mauser in the USA and .275 Rigby in the United Kingdom is a first-generation smokeless powder rimlessbottlenecked rifle cartridge. It was developed by Paul Mauser of the Mauser company in 1892 and adopted as a military cartridge by Spain in 1893. It was subsequently adopted by several other countries as the standard military cartridge. It is recognised as a milestone in modern cartridge design, and although now obsolete as a military cartridge, it remains in widespread international use as a sporting round. The 7×57mm has been described as “a ballistician’s delight”. Many sporting rifles in this calibre were made by British riflemakers, among whom John Rigby was prominent; and, catering for the British preference for calibres to be designated in inches, Rigby called this chambering the .275 bore after the measurement of a 7 mm rifle’s bore across the lands.
