The cylindro-conoidal bullet is a type of muzzleloading firearm projectile with a convexly cone-like front end ("nose") and a cylindrical rear body, invented by Captain John Norton of the British 34th Regiment in 1832. It had a cavitied base, so when fired, the thin concavity wall ("skirt") would expand outwards and seal up the bore diameter.
The Nessler ball, or balle Nessler, is a type of muzzle-loading musket bullet. It was developed to increase the accuracy and range of smoothbore muskets and was used in the Crimean War.
