If there is any good news about bismuth it's that most of it comes from China, followed by Mexico and Peru.
The process is a patented process and means if one were to use that process to make shot for sale, well you got trouble.
Looks like, from a casual search that it's got a 3% tin added to the bismuth.
From my reading it looks a little more complicated than just running it out your Littleton shotmaker into some antifreeze.
None of these for home use shotmakers, make shot in sizes that have much interest for a guy shooting waterfowl. The guy that owns the rights to littleton shotmaker claims that it's possible to make #5 and #6's. that's with lead of course. But when you pin him down he will tell you it's been done but only under special circumstances.
Of course one wonders if the drippers made for lead will work the same with bismuth, as they do with lead.
Lots of questions. It looks like the owner of the process is ASARCO.
