Different types of cannon balls recovered from the ''
Vasa'', which foundered in
1628.
'Round shot' is a type of projectile fired from
guns or
cannons.
A solid projectile made, in early times, from dressed stone but, by the 17th century, from iron. The most accurate projectile that could be fired by a smooth-bore
cannon, used to batter the wooden hulls of opposing ships, forts, or fixed emplacements, and as a long-range anti-personnel weapon.
Along with
pellet shot and
grapeshot, round shot was one of the early projectiles used in
firearms. As the name implies, round shot is
spherical with a diameter slightly less than the
bore of the firearm it is to be used in.
Round shot was popular during most of the
age of sail, being replaced after the invention by
Benjamin Robins of the
extruded bullet around the mid-19th century.
Round shot has the disadvantages of not being tightly fitted into the bore (to do so would cause jamming). This causes the shot to "rattle" down the gun barrel and leave the barrel at an angle without the use of a wadding or discarding
sabot.
Round shot has been totally replaced by modern
bullets in
small arms and by
shells in
artillery. Round shot is used in historical recreations and historical replica weapons.
Pellet shot (now simply called 'shot') is still used in
shotguns. Grape shot is still occasionally used in artillery - usually with an explosive spreader - for antipersonnel operations.
