Here's a little ditty you don't see every day .
I messed with the photo editing a little to try to better read it .......
This is an inspection and issue acceptance stamp on the but stock of an 1866 Chessipot (chass-poh , it's French it doesn't have to make sense) .
It fires a self contained nitrated paper cartridge , although the French used silk for the outer shell in arsenal prepared cartridges , that fire a .433 385 gr bullet 1350 fps with a charge of 86.4 gr of BP generally FFg .
Its a bolt action single shot breach loader needle fire type improved Dryse .
It stands 4'4" and was considered a light "dainty" rifle in it's era 1866-1875 at a svelte 10 lbs 6oz .
The silk encasement captured a significant amount of the powder fouling and acted as a fouling scrubber but also remained intact to the muzzle taking with it the fired musket cap and cartridge ash allowing for 30 or more shots before fouling stopped chambering . So should you find yourself in want of a caseless cartridge now you know what to look for .
Oh there were 2 million produced and this one was among the last produced under Napoleon III 1870 .
