Geno,
Will mention it and not just to Hornady, as non-toxics are eventually going to be required in more and more places.
In the meantime I thought of a couple alternatives. One would be to swage down Ballistic Products ITX non-toxic buckshot or roundballs to .25, since it's pretty dense stuff and while not as swageable as lead might work. If it would work, it would probably have to be taken down in 2-3 stages, but Lee Precision swaging dies are pretty cheap.
