The unround shot was either re-processed in another attempt to make round shot using the shot tower again, or used for applications which did not require round shot (e.g., split shot for fishing). [1] The hardness of lead shot is controlled through adding variable amounts of tin, antimony and arsenic, forming alloys. [1]
How a shot tower works The shot tower in Dubuque, Iowa. 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 ...
An anti-personnel weapon, similar to canister shot, but with the shot being contained in a canvas bag, and generally of a larger caliber. So called because of the resemblance of the clustered shot in the bag to a cluster of grapes on the vine. In one variation of this, the shot was held together by a coiled bar, and was spread by a fused charge ...
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.
The lead droplets would then fall 150 feet to become spherical and cool sufficiently to become rigid. At the bottom of the tower was large kettle of water for the shot to land in, in order to complete the cooling process and provide a soft enough landing to keep it from deforming. The finished shot was then marketed to hunters, traders and ...
Tungsten shot is a dense metal, too, providing a strong, fast and clean shot. Bismuth and tungsten are more expensive than both lead and steel. But copper has become another effective alternative.
Indiana DNR doesn't have the authority to ban lead bullets. But it is asking hunters to use alternatives that are not toxic to wildlife like eagles.
In 1775, William Watts, a plumber, started converting his house, near St Mary Redcliffe Church, into the world's first shot tower, in order to make lead shot by his innovative tower process. He did this by adding a tower atop his house, and by excavating a shaft into the soft sandstone below , achieving a total drop of around 90 feet (27 m).
