Another of my hobbies is artifact collecting. I also have found lots of old brass shotshell bases from the paper shell era while surface hunting old fields for arrow-heads. In Argentina the pass shooting on hilltops between the roosts and the feeding areas produces tremendous accumulations of plastic shot-wads. The outfitters do a good job of cleaning up the shell cases because there is a market for them, but the shot wads apparently have no utility and stay where they fall. Degradable substitutes would be a benefit...Geo
