Query: What was the Dreyse rifle's tactical range?
Context: The army was still equipped with the Dreyse needle gun of Battle of Königgrätz fame, which was by this time showing the age of its 25-year-old design. The rifle had a range of only 600 m (2,000 ft) and lacked the rubber breech seal that permitted aimed shots. The deficiencies of the needle gun were more than compensated for by the famous Krupp 6-pounder (3 kg) steel breech-loading cannons being issued to Prussian artillery batteries.
