DES MOINES, Iowa (AP) – The Iowa House has approved a resolution that would overturn a ban on the use of lead shot when hunting doves.  Backers of the resolution say the Natural Resources Commission overstepped its authority when writing rules governing the hunting of doves. That hunting was legalized by the Legislature last year. The House approved the resolution on a 68-27 vote Thursday, and the issue now goes to the Senate, where approval is likely.  Backers of the ban on lead shot say other animals can eat the lead and that can lead to sickness or death.  Opponents of the ban say lawmakers discussed the issue last year and decided not to ban lead shot. They argue regulators shouldn’t overturn that decision.
