The musket was the most popular firearm in the 17th century when Bastion III had the shape which you can see today. It was usually 160 cm long with the barrel being 115 cm long and its calibre was 18-20 mm. Lead bullets weighed up to 50 g. Muskets were muzzle-loading and at first were equipped with matchlocks and then with wheel locks. The classic matchlock gun held a burning slow match in a clamp at the end of a small curved lever - the serpentine. Upon the pulling of a lever (or in later models a trigger) protruding from the bottom of the gun and connected to the serpentine, the clamp dropped down, lowering the smouldering match into the flash pan and igniting the priming powder. The flash from the primer travelled through the touch hole igniting the main charge of propellant in the gun barrel. The wheel lock worked by spinning a spring-loaded steel wheel against a piece of pyrite to generate intense sparks which ignited gunpowder in a pan, flashing through a small touchhole to ignite the main charge in the firearm's barrel. The pyrite was clamped in vise jaws on a spring-loaded arm (or 'dog') which rested on the pan cover. When the trigger was pulled, the pan cover automatically opened and the wheel spun as the pyrite was pressed into contact. The range of musket fire did not exceed 300 m but the range of effective fire was only 130m. Since a musket weighed up to 7.5 kg, it was impossible to fire it without resting it on a support. A well-trained musketeer could fire every two minutes.
