Anybody ever try these typical styrofoam packing "peanuts" as smoothbore wadding? Seems to that cut in half they're about the right size and easily compress with no muss and no fuss, they're only mildly flammable, and if memory serves, they're even biodegradable. Compared to what typical shotgun shooters are discharging into the environment these packing peanuts are nothing. Opinions? Comments? Actual usage?
