Close up of .75 calibre
Brown Bess musket lock (firing sequence)
In this series of 12 photos, taken about 1/30 of a second apart, you can see the short duration of the "Flash in the Pan" as the priming powder is burnt followed by the considerable vibration of the recoil as the main charge fires. The gun is a .75 calibre smoothbore flintlock musket known as a "Brown Bess", firing a 540 grain lead ball and it can generate a considerable 'kick' on firing. See also the view of the gun being fired.
