Appears that the shotshell mfgrs are going to be coming out with biodegradable wads over the next few yrs, at least they are working on it, and have released some of them. I suppose it helps that some members of the EU have mandated them. I have no issue with the idea, but, as usual, at the moment, they are premium priced. Not sure there is a whole bunch of "new" tech in it except perhaps the shot cups. Strikes me as an opportunity to try to earn some points with the greenies, certainly won't hurt their image in the world today. I should think the mfgrs will jump all over this asap. Will have to keep your ammo dry.
