double-base smokeless powder, resulting in nearly 40% higher muzzle velocity and 30% more muzzle energy. Receiver and magazine The Gewehr 1888 is a further development of the receiver and bolt of the Gewehr 1871 combined with a Mannlicher magazine. It has a receiver with a "split bridge" (i.e., the bolt passes through the receiver and locks in front of the rear bridge); a rotating bolt head; and the characteristic Mannlicher-style "packet loading" or "en-bloc" system in which cartridges are loaded into a steel carrier (an en bloc clip) which is inserted into the magazine, where it holds the cartridges in alignment over a spring. As shots are fired the clip remains in place until the last round is chambered, at which point it drops through a hole in the bottom of the rifle. This system was used in almost all Mannlicher designs and derivatives, and while it allows for speedy reloading, it also creates an entry point for dirt. To settle a patent infringement claim by Steyr-Mannlicher, Germany contracted the Austro-Hungarian company to be one of the manufacturers of Gewehr 88s, and Mannlicher together with Otto Schönauer derived from the Mauser-Schlegelmilch design a whole family of turn-bolt actions, the last of which was serially produced until 1970s. Bolt and barrel The commission rifle's bolt action design was a commission modified Mauser action. The barrel design and rifling were virtually copied from the French Lebel. The rifle has an odd appearance as the entire 'floating' barrel is encased in a sheet metal tube for protection, but with the tube removed the rifle looks rather modern. This tube was intended to increase accuracy by preventing the barrel from directly contacting the stock, but in practice it increased the risk of rusting by providing a space for water to be trapped if the rifle was exposed to harsh conditions. The Karabiner 88 utilized a different bolt handle, which resembled those found on commercial sporting rifles. Service history Some early models had flaws due to rushed ammunition production. This was used in 1892 by the then notorious anti-Semitic agitator Hermann Ahlwardt, member of the German Reichstag, to spread an anti-semitic conspiracy theory. Many of the Gewehr 88-rifles were produced by the armament manufacturer Loewe & Company, whose chairman was Jewish entrepreneur Isidor Loewe. Isidor Loewe also held a controlling interest in the Waffenfabrik Mauser. According to Ahlwardt's claims, Loewe would either deliberately supply the
