Boss copper-plated bismuth shot shells

[Stan Hillis]

I have wondered the same thing, Frank. I've combed their website looking for clues but can only find references to copper plating. I'm aware of the difference, and that in other settings, such as nickel plating, it is very hard to find true plated shot. I load a specialty load for doves with nickel plated shot from Precision Reloading that is specified as being true plating, electro-plated. I read somewhere once that they source it from Italy.

But, given the lack of specifics on the BOSS shot I wonder, like you.
