Perhaps I should have said "not outrageously toxic" or something of that sort, because that does not sound worse than the stuff we make normal bullets out of - lead.

Lead doesn't shatter the way uranium does, so it's less inclined to form a breathable dust on impact.

That's true! Lead does tend to stay more clumped up than uranium dust. But isn't it also easier for lead to become bioavailable and/or enter the water supply?
