Hall Model M1819 Rifle in the Original Flint



Hall Model M1819 Rifle in the Original Flint - The M1819 Hall rifle was a single-shot breech-loading rifle designed by John Hancock Hall, patented on May 21, 1811, and adopted by the U.S. Army in 1819. It was preceded by the Harpers Ferry Model 1803. It used a pivoting chamber breech design and was made with either flintlock or percussion cap ignition systems. The main years of production were from the 1820s to the 1830s at the Harpers Ferry Arsenal. This was the first breech-loading rifle to be adopted in large numbers by any nation’s army, but not the first breech-loading military rifle – the Ferguson rifle was used briefly by the British Army in the American Revolutionary War. Breech-loading rifles remained overshadowed by common muskets and muzzle loading rifles so prevalent in the early 19th century. The early flintlocks were mostly converted to percussion ignition.

This original flintlock model has a 32.5-inch barrel rifled with 16 “clockwise” (right-hand) grooves making a turn in 96 inches. The muzzle was reamed to a depth of 1.5 inches and had an appearance of a smoothbore. Overall length is 52.5 inches, and weight without bayonet is 10.25 pounds. The rifle fired a .525 ball weighing 220 grains (one-half ounce), using a 100-grain powder charge and 10 grains of fine powder primer. This example exhibits a nice, original browning and a fine condition, oil-finished walnut stock, exhibiting a wonderful “feathered” appearance. The action  and associated mechanics of the gun are excellent. For some reason, when we obtained the weapon, it had a recently replaced frizzen, which has been browned to match the rest of the finish of the gun. All other parts are completely original.

The back several inches of the “barrel” (the chamber) is a separate piece that pivots upwards from the front for reloading. In essence, the weapon was still loaded front to back, but in a short section, similar in concept to loading a cylinder of an early cap-and-ball revolver.

The development was primarily the work of Hall, who had been working on a design in the first two decades of the 19th century, receiving critical patents during the time. The work caught the interest of the Army, which led to a contract, at the end of the latter decade. The breech-loading design was made possible by Hall’s focus on using carefully machined components to form a seal, but still allowing enough tolerance for the breech to be opened easily. The Hall rifle offered a significant increase in rate of fire over muzzleloading rifles and muskets; however, the design suffered from a gas leak around the interface of the removable chamber and the bore, resulting in the necessity of a heavier powder charge that still produced much less muzzle velocity than its muzzleloading competitors. No serious efforts were made to develop a seal to reduce the loss of gas from the breech. The penetrating ability of its .52-caliber ball for the rifle was only one third of that of the muzzleloaders, and the muzzle velocity of the carbine was 25 percent lower than that of the Jenks “Mule Ear” carbine, despite having similar barrel lengths and identical 70-grain powder charges.

Thousands of rifles were made, though the troops and many leaders preferred the simplicity and lower costs of muzzle-loaded weapons; however, the advantages were clear, and breech-loading designs would grow to dominate rifle procurement after the Civil War. Many of the lessons learned by Hall would benefit designers of the next generation of breech-loaders such as the Sharps rifle (1848), Spencer carbine (1860), and others.

The Halls were used against Indians and in smaller conflicts. Some saw service in the Civil War; however, by this time, many of the Hall rifles were worn out after 30 years of use. In the Battle of San Pascual in California, the Halls managed to demonstrate that breech-loading was not practical in rain. With paper cartridges, it was impossible to keep the powder dry. Kearny’s troops would have fared better with muzzleloaders.

As part of the process, Hall built his own shops and machinery at Harper’s Ferry, and along with inventing this weapon, he invented many machines, paving the way for uniform manufacturing of weapons with interchangeable parts. The ruins of his shops are still visible today.
