(GunReports.com) — A decision by a panel of Iowa lawmakers last week allowing lead ammunition for the upcoming dove hunting season is the latest salvo in a national battle over whether hunters should be permitted to use traditional lead shot and bullets.Iowa is bucking the trend in not stiffening regulations on lead shot, at least for this season. Almost two-thirds of states, including Iowa, ban lead ammo in some situations.Gov. Terry Branstad waded into the controversy Monday, not commenting on the use of lead shot directly, but portraying the legislators’ vote as a necessary step to rein in the state’s Department of Natural Resources and the Natural Resources Commission, which he said had overstepped their bounds. Legislators had made the same argument.http://www.desmoinesregister.com/article/20110823/NEWS10/308230007/-1/GALLERY_ARRAY/Lead-shot-skirmish-Iowa-part-national-battle
