After about 200 years, the next major development was the flintlock. It used a flint striking mechanism. Another improvement replaced the flashpan with a smaller “priming pan” that held a smaller amount of black powder. It also contained an opening into the breach to ignite the main powder charge. A small piece of steel (called a “frizzen”) was mounted to the top of the priming pan. When the trigger was pulled the mechanism created a spark igniting the powder in barrel. When the powder and ball were loaded into the barrel, it was then tamped (pushed) down with the ramrod. The hammer was pulled back to the first click, called "half-cocked". To make the weapon ready to fire, the hammer was pulled back to the "full-cocked" position. When the trigger was pulled, a spring caused the hammer to fall igniting the charge. Flintlocks were the main firearm for the next 200 to 300 years before being replaced by percussion cap guns.
