Bolt action rifle is a weapon, which requires a manual operation to reload a weapon prior to each shot. Term "bolt action"
comes from the "bolt" - a part of the weapon that is used to feed cartridges into the chamber and to lock the barrel
upon the fire. This part also is more generally known as "breech block", but the term "bolt" is usually
referred to the longitudinally movable breech block. So, to fire each shot from bolt action rifle, one must manually unlock
the bolt, open it to extract and eject spent case, close the bolt, feeding a fresh round into the chamber simultaneously,
and then lock the bolt. When trigger is pulled, rifle goes off and another set of manipulations described above is required
prior to the next shot can be fired. Bolt action rifles could be further divided in numerous sub-categories, such as single-shot
or magazine-fed rifles, rotating bolt or straight pull bolt action rifles etc,First bolt action rifles appeared somewhere
in the mid-XIX century..
