Used to describe a rifle which to load a round into the chamber and eject the spent cassing needs to have the bolt opened and closed by hand. Most WWII rifles were bolt action (No4 .303) and modern sniper rifles and hunting rifles are usually bolt action

The offical name for what a civilian may call a bullet. The round is the lead projectile, the copper casing (which is ejected after being discharged) and the charge or propelent.
