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.
After the lead shot cools, it is washed, then dried, and small amounts of graphite are finally added to prevent clumping of the lead shot. Lead shot larger than about #5 tends to clump badly when fed through tubes, even when graphite is used, whereas lead shot smaller than about #6 tends not to clump when fed through tubes when graphite is used.
The tower was one of the earliest built to manufacture lead shot using the method pioneered in the 1780s by the Bristol inventor William Watts. [1] Molten lead was poured through a pierced copper plate or sieve at the top of the tower, with the droplets forming perfect spheres by surface tension during the fall; the spherical drops were then cooled in a vat of water at the base.

The earliest airgun pellets are actually small round lead shots similar to those used in muskets.First popularized by the Daisy BB Gun in the 1890s, a spring-piston airgun that shot "BB"-size birdshots, the .180-caliber lead shots were later replaced by the lighter .175-caliber steel shots modified from bearing balls, and remained popular as a plinking/pest shooting projectile due to the ...
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. Lead shot in deer carcasses is toxic to eagles ...
The Jackson Ferry Shot Tower is a 75-foot (23 m) tall tower used for manufacturing lead shot located in Wythe County, Virginia [3] and now adjacent to the New River Trail State Park, a lineal rail trail park connecting the historic towns of Pulaski and Galax, Virginia.
Inspired by a robotic hockey slap-shot machine built by one of his professors, he started creating designs for a system that would eventually become the Arc machine. It wasn’t a seamless process.
BB pistol with CO 2 cartridges and BBs. A BB gun is a type of air gun designed to shoot metallic spherical projectiles called BBs (not to be confused with similar-looking bearing balls), which are approximately the same size as BB-size lead birdshot used in shotguns (0.180 in or 4.6 mm in diameter).
