"It was fun to fire cannons as they were meant to be used, and see what happens," Twist said. In one technique, "You fire slightly below the target. It hits the ground, skips, kicks up dirt, and you hear the impact on the side of the tank.
"It's a very loud metallic 'Thunk!' when a 12-pound projectile hits an immovable chunk of iron," he said.

The most visual effect comes when a solid shot sails into the woods "and trees start falling down."
They also fired rounds of smaller projectiles called grapeshot, which got Twist appreciating the resolve of Civil War soldiers who fought 150 years ago.
