# Smith carbine

The Smith Carbine was a .50 caliber breech-loading black powder percussion rifle patented by Gilbert Smith on June 23, 1857 and successfully completed the military trials of the late 1850s. It was used by various cavalry units during the American Civil War.
The Smith Carbine was unique in that it broke apart in the middle for loading and it used rubber and paper/brass foil cartridges which sealed the gases in the breech. The downside was that these rubber cartridges were sometimes difficult to remove from a hot breech.
The carbines were built by Massachusetts Arms Company of Chicopee Falls, Massachusetts; the American Machine Works in Springfield, Massachusetts; or the American Arms Company in Chicopee Falls. The name of the distributor for the manufacturer, Poultney & Trimble of Baltimore, Maryland, is often stamped on the carbine's receivers.

## Smith Carbine Replica

Italien gun manufacturer F.LLI Pietta produced a fairly good quality Smith Carbine replica in "Artillery" and "Cavalry" (with saddle ring) versions. Although it seems, after a final production run in 2024, F.LLI Pietta stopped the production of the Smith Carbine. As of late 2024, they are still available in small numbers from several vendors in Europe.

## Smith Carbine Cartridge

Modern reusable cartridges cases are available from several manufacturers made from polyamide (black, contains 30-35 grain BP), polyurethane rubber (transparent red, with brass flash hole liner, 35-40 grain BP) and turned brass (various models, 30-50 grain BP). It is also relatively easy to build period correct one-way paper cartridge cases from packaging paper and strong aluminium foil (sourced from beer or soda cans).
While the thick walled, turned brass cartridges last almost indefinitely and can be easily reloaded, they don't provide an almost 100% gas seal like the "plastic" and paper cartridges. According to users, the reusable "plastic" cartridge cases last about 15-20 shots (similar to modern drawn cartridge cases).

## Smith Carbine bullets

Period correct Smith Carbine bullet moulds are available from Eras Gone Bullets and others. The Smith Carbine bullets have about .515 diameter (13,1mm) and weight about 365 grains. To fit the brass cases, the bullets have to be sized to .508-.510 diameter (12,9-12,95mm).

In 1865 the Argentine Armed Forces acquired through Schuyler, Hartley & Graham around 400 examples to be used by cavalry and other forces in the fight against the indians and the rebellions in the interior. A few were sent to the front in Paraguay.
In 1871, 371 were issued to line forces and four to the borders. Some were used on the western frontier, .50 Smith bullets were exacated at Fort General Paz (today Carlos Casares).
They remained in use for line forces up to 1874 (the last inventory of the Artillery Park where they are mentioned dates from 1874), afterwards they were used by the Guardia National of Buenos Aires and other Buenos Aires volunteer forces until 1881.
