Lead shot or lead balls are used in ammunition, radiation shielding and as ballast lead. By ammunition we all know what it's used for. Lead shot used for radiation shielding is a more human way of using shot. By filling up the space between two elements you can create a radiation protected shield. Used as ballast weight you can find lead shot in your curtains for example. Filling up the keel of a boat is another way to use lead shots as ballast weight.
Packing Packed in bags. The weight per bag is different per lead shot manufacturer but will not exceed 25 kg.
