in the 19. century it was space age technology

you are advanced not only knowing that there was a chassepot but also the italian carcano needlefire rifle. btw ,another rifle but from the same Carcano who invent the italian bolt action rifle 20 years later.
the carcano was only an interim solution to get a new breech loader from the old muzzle loaders like the snider rifle in britain. italian and france had than a pur shotgun hunting culture with shooting the rare big game only with buckshot. there are some civil made chassepot hunting cartridges showing the rifle was used for hunting in france than but the rifle itself was not "sporterized" like some chassepot in germany.

I got a fine work yesterday, my job is it to make a Dreyse needle fire hunting rifle working again were are all part of the bolt are lost. unknown design till now the only one exist we can only guess.
It shoot's a .50 caliber bullet with a gas tight paper cartridge than.

military rifle
my chassepot project
the poor Dreyse stalking rilfe

notice how similar the action is to the bigger military rifle

the bolt was some kind of a missing link to the Dreyse Patent rifle than still in production

the needle fire rifle

made 5 years later for center fire cartridges, different bolt
