Answer: (4) (iv), (iii), (i), (ii)

-> A ramrod is a metal or wooden piece that is used to push the projectile into the barrel against the propellant for loading the muzzleloading firearms.
-> Chamber marks are seen during the loading and unloading of cartilage mainly by the action of extractor and ejector.
-> Rifling marks are always made by the bullets traveling through a rifled barrel.
-> Choking of the barrel is a tapered constriction of a smooth barrel at the muzzle end to control the dispersion rate of pellets.

42. Assertion (A): The penetration power of shotgun is more than service rifle.
