The Hall rifles and carbines were loaded using a combustible paper cartridge inserted into the upward tilting breechblock. Army as the Model 1819 Hall Breech Loading Rifle. The first was invented by John Hall and patented c.

The only two flintlock breech loaders to be produced in quantity were the Hall and the Crespi. This system was improved in the 1770s by Colonel Patrick Ferguson and 100 experimental rifles used in the American Revolutionary War. The plug stayed attached to the barrel and the ball and powder were loaded from the top. The barrel could be opened by 3 revolutions of the triggerguard, to which it was attached. One of the more successful was the system built by Isaac de la Chaumette starting in 1704. A large number of sporting rifles were made with this system, as it allowed easier loading compared with muzzle loading with a tight fitting bullet and patch. Another type has a removable screw plug set into the side or top or bottom of the barrel. This type is known as a Queen Anne pistol because it was during her reign that it became popular (although it was actually introduced in the reign of King William III). This is more practical on pistols because of the shorter barrel length. The most popular action has a barrel which was unscrewed from the rest of the gun. Various breech-loading flintlocks were developed starting around 1650. This instantly changed the calculus of infantry combat by one calculation, a formation equipped entirely with flintlocks could output ten times as many shots in an equivalent period of time as a typical early 17th century pike and shot formation equipped with matchlocks (pike:shot ratio of 3:2). Compared to the earlier matchlock, flintlocks could be reloaded roughly twice as fast, misfired far less often, and were easier to use in various environments due to the fact that they did not require a lit match. The 'true' flintlock was less expensive to manufacture than earlier flintlocks, which along with general economic development allowed every European soldier to have one by the 18th century. The last major European power to standardize the flintlock was the Holy Roman Empire, when in 1702 the Emperor instituted a new regulation that all matchlocks were to be converted or scrapped. These flintlocks were in use for alongside older firearms such as matchlocks, wheellocks, and miquelet locks for nearly a hundred years. Examples of early flintlock muskets can be seen in the painting 'Marie de' Medici as Bellona' by Rubens (painted around 1622-25). The new flintlock system quickly became popular, and was known and used in various forms throughout Europe by 1630, although older flintlock systems continued to be used for some time. Le Bourgeoys fitted these various features together to create what became known as the flintlock or true flintlock. The development of firearm lock mechanisms had proceeded from the matchlock to wheellock to the earlier flintlocks ( snaplock, snaphance, miquelet, and doglock) in the previous two centuries, and each type had been an improvement, contributing design features to later firearms which were useful. Their cost and delicacy limited their use for example around 1662, only 1 in 6 firearms used by the British royal army was a snaphaunce, the rest being matchlocks. The first proto-flintlock was the snaplock, which was probably invented shortly before 1517 and was inarguably in use by 1547. However, firearms using some form of flint ignition mechanism had already been in use for over half a century.
