c) Inceridiary bullet
d) Tumbling bullet
Correct Answer - A
Ans. is ‘a’ i.e., Tandem bullet [Ref SK Singhal 4thle p. 188]
Varieties of bullets are :-
i) Incendiary (igniting) bullet :
The tip of bullet contains self igniting material e.g. barium nitrate and
powdered aluminium and magnesium (in the past, phosphorus was
used), so that it catches fire on hitting the target. It is used to cause
fire in usually inflammable targets like fuel tanks (of air crafts etc).
ii) Explosive bullet :
The tip contains a detonator or lead azide, so that the bullet
explodes on hitting the target.
iii) Dum-dum bullet (expanding bullet):
It is a jacketed bullet with is nose tip chiseled or cut off It is designed
to increase in diameter and expand upon striking the target, thus
producing larger diameter wounds of limited penetration.
iv) Tandem bullet (Piggey tail bullet) :
It is called one-behind-other bullet because two bullets are ejected
one after the other, when first bullet failed to leave the burrel and is
ejected by subsequently fired bullet.
Therefore, both enter body through same enterance wound (some
imes, they may enter through different entries), but the wounds of
exit are always two.
