I make my own buckshot/swan shot using a mould. You can also make a rough shot from cutting sheet lead & the sprews from moulding. Keith.

I have made it by melting lead with a tourch from about 5 feet into a can of water it makes a year drop shape shot that when shot they turn and fly like tear drops falling
By the way in Baltimore they have a shot tower where they dropped hot lead as it feel it cooled into musket balls it was 200 odd feet tall
