A Steyr-Mannlicher M1895.
The Steyr-Mannlicher M1895 rifle is a bolt-action rifle, designed by Ferdinand Ritter von Mannlicher that used a refined version of his
Austro-Hungarian soldiers with M1895 carbines during World War One
revolutionary straight-pull action. It was so so so so good and they used it a lot. They used it in world war one, i think. The rifle used a 8mm Calibre and ended up to be fitted with 3 types of Cartridges, the 8x50mmR Mannlicher, 8x56mmR and the 7.92x57mm Mauser. The rifle was fed a 5 round stripper clip. The Steyr-Mannlicher M1895 was used in the Boxer Rebellion, Balkan Wars, World War I and II, and over 3,000,000 were built. The rifle was nicknamed the "Ruck-Zuck" by German soldiers for its speedy reloading.
In combat, the Steyr-Mannlicher M1895 proved to be a strong and accurate rifle. The ammunition was loaded from the top which provided quick reloads along with the straight-pull action. The rifle could also be equipped with a bayonet and a telescopic sight. The rifles were sensitive to mud and dirt and the straight pull bolt lacked the powerful initial extraction, provided by most rotating bolt actions. A large opening at the bottom of the magazine easily collected the dirt and dust into the magazine. The en bloc clip loading system does not allow the partially full magazine to be refilled without removing the non-empty clip first. The use of rimmed ammunition resulted in the non-symmetric clip which could be inserted into the action only with one side down; the upper side of the clip has stamped serrations to hold it while loading.
