You are correct. Cattle eat them too.
They are indigestible, and they was up into a big nasty plastic gob in the animals guts. I’ve seen many pictures of them.

Lead brings more subtle problems to the mix.

The bottom line, is the bottom line.

The public won’t allow for the burying of end loader buckets full of dead game, and the marketplace that consumes it won’t buy it if it was shot with lead.

So other than for casual shooters, what are they supposed to do?
Obviously, scale down the shooting volume, and totally upend an entire industry. And all the estates that support it, and all the people that work in it, and all the communities that depend on it.

Out there doing it best I can.
