Civil War Cannon / Shotgun Silencer

Overview

Will and his team of gunsmiths are hired to do the impossible — build a shotgun silencer. In the meantime, Will's friend Glenn shows up with a rare Civil War cannon worth $250,000 that the owner wants to fire 150 years after it last saw action. Daughter Stephanie keeps the shop running as Will does the research to see if the cannon can be fired safely.
