Twelve days ago the Chinese, the main supplier of bismuth, shut off exporting five critical metals to the US including bismuth and tungsten. If you look around you will see it's pretty slim pickings from Rotometals and Ballistic Products. It appears Precision reloading has stopped selling bismuth shot.
I read Boss Ammo gets 90% of it's bismuth from China on another forum so the makers of factory shells may have trouble getting it as well.
If you shoot game on public lands where non tox shot is required or you hunt waterfowl and use bismuth I would say we are probably headed for a limited supply and higher prices.
As Mike Koneski says if you use it, buy it when you see it.
