The Iowa Legislature is debating the ban on lead shot for dove hunting in the state. Many hunter advocacy groups say that banning lead shot would be a poor decision, as it’s cheaper and has better shooting characteristics then alternative ammunition. Wildlife advocacy groups argue that lead contamination is a dangerous factor for ecosystems, and often predatory creatures are found dead with high lead contents. Eric Hoffman, a DNR conservation officer in Marion county tells KNIA/KRLS News that alternatives like steel shot can take some adjustment to use, but generally the limitations of the shooter are a more significant factor then the limitations of the equipment they use. Hoffman says that the DNR offers shooting classes for bird hunters. Many other states require non toxic shot be used for all bird hunting, A national ban on lead for waterfowl hunting was enacted in 1991.
