Dreyse needle gun
The Austrians instead used a variant of Manton's tube lock in their Augustin musket until the conventional caplock Lorenz rifle was introduced in 1855. The first practical solution for the problem of handling percussion caps in battle was the Prussian 1841 (Dreyse needle gun), which used a long needle to penetrate a paper cartridge filled with black powder and strike the percussion cap that was fastened to the base of the bullet. While it had a number of problems, it was widely used by the Prussians and other German states in the mid-nineteenth century and was a major factor in the 1866 Austro-Prussian War. The needle gun originally fired paper cartridges containing a bullet, powder charge and percussion cap, but by the time of the Franco-Prussian War this had evolved into modern brass ammunition.
