The hole provides external access of an ignition spark into the breech chamber of the barrel (where the combustion of the propellant occurs), either with a slow match , a linstock or a flash pan ignited by some type of pyrite- or flint-based gunlock (snaplock, snaphaunce, and flintlock), which will initiate the combustion of the main gunpowder ...
Flintlock mechanism The frizzen , historically called the "hammer" or the steel , [ 1 ] [ 2 ] is an L-shaped piece of steel hinged at the front used in flintlock firearms . The frizzen is held in one of two positions, opened or closed, by a leaf spring .
The flash pan was at first attached to the gun barrel, but was later moved to the lock plate of the gun. A small amount of finely ground gunpowder is placed in the flash pan and ignited. The flash of flame travels through the touch hole igniting the main charge of propellant inside the barrel. Unlike the cannon, it was not necessary (or ...
The Belton flintlock was a repeating flintlock design using superposed loads, conceived by Philadelphia, Pennsylvania, resident Joseph Belton some time prior to 1777. The musket design was offered by Belton to the newly formed Continental Congress in 1777.
The wheel-lock enjoyed only a brief period of popularity before being superseded by a simpler, more robust design. The "flintlock", like the wheel-lock, used a flashpan and a spark to ignite the powder. As the name implies, the flintlock used flint rather than iron pyrite. The flint was held in a spring-loaded arm, called the "cock" from the ...
The flint strikes from the steel a shower of white hot steel shavings (sparks) which fall towards the priming powder held in the flash pan. The flash from the pan's ignited primer travels (unless there is only a "flash in the pan") through the touch hole into the firing chamber at the rear of the barrel, and ignites the main charge of gunpowder ...
The target was a wooden shield the size of an infantry or a cavalry line. The results of the practice were as follows: at a distance of 100 yards (91 m) 53% hits, 200 yards (180 m) 30% hits, 300 yards (270 m) 23% hits. The accuracy of the Brown Bess was in line with most other smoothbore muskets of the 18th to 19th centuries.
The cylinder is bored straight through with no step. Later versions used an inside the case lubricated bullet of .357" diameter instead of the original .38" with a reduction in bore diameter. The difference in .38 Special bullet diameter and case diameter reflects the thickness of the case mouth (approximately 11/1000-inch per side).
