This video has been updated from its original form to remove a reference to an erroneous claim that it did not effectively obturate, and was thus fired from the hip. For a great video showing live fire of the Dreyse
The Dreyse needle rifle (or zundnadelgewehr, which translates to needle firing rifle) was a major step forward in military rifle technology, although it did not remain at the forefront for very long (much like the Spencer repeating rifle in that regard). It used a paper cartridge with an integrated percussion cap primer, allowing the shooter to carry fully self-contained ammunition. It was a breech-loading bolt action, and the combination of these features gave it a much higher rate of fire than the muzzleloading rifles it replaced.
