I had never heard of it but if it is the same cost as bismuth, I am not sure as the advantage. They try to address this with all the testing concerning fracture but this seems to be a problem no one has reported. The rest of the discussion seems to center around a problem that has already been solved. Modern mono controlled expansion bullets have pretty much revolutionized the whole world of hunting to the extent that the entire killing power results relative to caliber have changed. With a price near bismuth you would end up with expensive old technology bullets. That is a flat no go.
