Thanks everyone. I have had a hard time finding nontoxic shot, and let me tell you deciphering the differences has been a pain.

I haven't got around to using my Bess for waterfowl yet, but for close to 20 years before we had to switch away from lead, I used a NA double 12 not only for waterfowl, but also for ptarmigan, snowshoe hare and even a few pheasant hunts. Never a prob, and in fact I kept the second barrel in reserve in case I needed a "quick reload" for a followup shot.
I let that double go before alternatives emerged, simply because I couldn't shoot steel through it. But a lot of shooting with steel and later alternates in cartridge guns taught me one thing. You not only need larger steel to the job, you need high velocity.
I point that out, because high velocity just doesn't come down the pike with black powder. Good patterning and excellent game performance with lead comes down around 1,000 fps. But any time I've shot steel loads down in the 1,200 fps range, crippling went through the roof. I won't even shoot a steel load these days that's less than 1,400 fps and I'll go to lighter payloads in favor of more velocity.
I'd go for the densest alternative you can get, because I'm convinced you'll need it for best killing at the low velocities of a ML. As I head back into ML waterfowl hunting myself, that's the path I'm taking.
