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.
It was originally named the MMJ 5.7mm [1] by its designer and is also known in the U.S. as the 5.7mm Johnson, the Johnson MMJ 5.7mm Spitfire, and the .22 Johnson, (or 5.7×33mm internationally).

A bullet can be made of virtually anything (see below), but lead is the traditional material of choice because of its high density, malleability, ductility, and low cost of production. However, at speeds greater than 300 m/s (980 ft/s), pure lead will melt more and deposit fouling in rifled bores at an ever-increasing rate.

Most tips are made of polyoxymethylene, although some manufacturers have used polyester urethane-methylenebis(phenylisocyanate) copolymer. [1] Upon impact, the plastic drives into the hollow point and the bullet performs like a standard hollow-point, expanding ("mushrooming") to a larger diameter.
