Bliemeister method
From Wikipedia, the free encyclopedia
The Bliemeister method, likely a misspelling of the German word "Bleimeister" (Lead Master), is the modern method of making lead shot in small sizes, replacing the shot tower. Metered molten lead is dropped a very short distance (quarter inch, rather than 150-300 feet as a shot tower might use) into hot water or another hot coolant, and rolled along an incline underwater to round the balls. The temperature of the water is controlled according to the cooling rate, which depends on the size of the shot as well as the purity of the lead. Antimony, added for hardness, raises the melting point of lead.[1]
Machines such as the "Incredible Shotmaker" allow hunters to make their own lead shot at home by the Bliemeister process out of scrap lead such as automobile wheelweights.
