From the bronze Tsar Puschka with a trunk of 120 cm diameter nobody ever shot. The master Ivan Chokhov casted the Tsar Puschka in 1586. The tool didn't participate in military operations though it was expected to fire not only stone kernels, but also a case-shot. The cast iron kernels lying near the Tsar Puschka from the middle of the 19th century actually don't fit her.
