Lead shot. Shot is a collective term for small spheres or pellets, often made of lead.These have been projected from slings since ancient times and were the original projectiles for shotguns and are still fired primarily from shotguns and grenade launchers, while they are less commonly used in riot guns.
Lead shot-related waterfowl poisonings were first documented in the US in the 1880s. [57] By 1919, the spent lead pellets from waterfowl hunting was positively identified as the source of waterfowl deaths. [313] Lead shot has been banned for hunting waterfowl in several countries, [57] including the US in 1991 and Canada in 1997. [314]
A shot tower is a tower designed for the production of small-diameter shot balls by free fall of molten lead, which is then caught in a water basin. The shot is primarily used for projectiles in shotguns , and for ballast , radiation shielding , and other applications for which small lead balls are useful.
A second shot tower was built in 1857. [2] A mill stream was used to power much of the machinery in the smelter. [8] A process had been discovered in the 1770s whereby additional quantities of lead could be extracted from the fumes emitted by reverberatory furnaces if the vapours could be trapped long enough to precipitate the lead.

Lead shot is still the best ballistic performer, but environmental restrictions on the use of lead, especially with waterfowl, require steel, bismuth, or tungsten composites. Steel, being significantly less dense than lead, requires larger shot sizes, but is a good choice when lead is not legal and cost is a consideration.
Lead (/ l ɛ d /) is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to ...
Dubuque in 1865, the shot tower can be seen on the far right edge. Bridges on the Mississippi, at Dubuque, an 1872 wood engraving showing the tower in the center. The tower was built in 1856 to provide lead shot. The invention of the shot tower enabled economical production of many nearly perfect lead spheres of the right size to fit in a shot ...
Round shot or solid shot or a cannonball or simply ball A solid spherical 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 ...
