*Chassepot Info*

The Chassepot, officially known as Fusil modèle 1866, was a bolt action military breechloading rifle, famous as the arm of the French forces in the Franco-Prussian War of 1870/1871. It replaced an assortment of Minié muzzleloading rifles many of which were converted in 1867 to breech loading (the Tabatière rifles). A great improvement to existing military rifles in 1866, the Chassepot marked the commencement of the era of modern bolt action, breech-loading, military rifles. Beginning in 1874, the rifle was easily converted to fire metallic cartridges (under the name of Gras rifle), a step which would have been impossible to achieve with the Dreyse needle rifle.

The breech was closed by a bolt similar to those of more modern rifles to follow. Amongst the technical features of interest introduced in 1866 on the Chassepot rifle was the method of obturation of the bolt by a segmented rubber ring which expanded under gas pressure and thus sealed the breech when the shot was fired. This simple yet effective technology was successfully adapted to artillery in 1877 by Colonel de Bange, who invented grease-impregnated asbestos pads to seal the breech of his new cannons (the De Bange system).

The Chassepot used a paper cartridge, that many refer to as being ‘combustible’, whereas in reality it was quite the opposite. It held an 11mm (.43 inch) round-headed cylindro-conoidal lead bullet that was wax paper patched. An inverted standard percussion cap was at the rear of the paper cartridge and hidden inside. It was fired by the Chassepot’s needle (a sharply pointed firing pin) upon pressing the trigger.
