While the gun design been favorable by the Russian Navy's brass, the innovative rocket darts idea been rejected in favor of the more traditional gunpowder ammunition variants. In extremely cold temperatures, the brass monkey shrank more than the iron cannon balls, and the stack of balls would collapse—or perhaps ice which formed under the balls pushed them up enough to break them loose. The driving force for recovery and recrystallization is associated with the strain energy stored in the crystal as a result of cold work. C485 - (Naval Brass Leaded) Similar to C464 the addition of lead to C485 provides a high degree of machine-ability.
