Lead shot is small balls of lead, traditionally made using a shot
tower. It is used for a variety of purposes. One use of shot is in
shotguns.Lead shot has been used to provide variable weight in
stress testing systems. Shot pours from a hopper into a basket,
which is connected to the test item. When the test item fractures,
the chute closes and the mass of the lead shot in the basket is used
to calculate the fracture stress of the item. Shot comes in three
sizes: B, BB and BBB.
Split shot, that is shot cut half through has been commonly used
as a line weight in angling. Lead is used for bullets and shot,
chiefly because of its high density. Shot alloys have been given as
99.8 Pb, 0.2 As, or 94 Pb, 6 Sb.
