BrownBear said:Can you provide details? I'm especially curious about casting temp, fill success (or failure) rate when casting, and as-cast diameter compared to lead. Also curious about weight comparison with lead balls from the same mold.
Do you remember what your % of bismuth to tin was? It might be worth experimenting with a higher % of tin in the mix. That should make the resulting ball more malleable, and reduce the chance of fracturing.Grey Whiskers said:I recovered 2 of the balls from sandy soil. One had mushroomed and the other had broken in two.

Interesting experiment, thanks for posting your results.
