A) Lead-free toy soldiers in commercial use may contain tin, copper, silver, Bismuth, indium, zinc, antimony and traces of other metals. As tin is the main ingredient in these alloys it would be pointless using them as tin shot is already available. Tin is much softer than steel (soft iron) shot and is slightly cheaper than Bismuth, making it a potential alternative for use in older guns for shooting game and pests at short range.
