They banned lead shot in 2005, now they are re-examining it:
The organisation criticised the ban on the grounds that it lacked a solid evidential basis and that the use of alternative ammunition posed animal welfare risks. Non-lead ammunition does not kill as cleanly or as efficiently as lead, and therefore causes unnecessary suffering to quarry, the JI has argued. It also maintains that the potential adverse effects of such substitute materials on health and the environment have not been studied in sufficient detail.
The typical substitute for lead is bismuth, which is nearly as dense as malleable as lead. The problem is that almost all the bismuth production is the world today is a byproduct of lead production. It’s only about twice as common as gold is. There is essentially no way for the shooting sports to function solely on lead substitutes. While Norway may be poised to repeal its law, we’re going backwards here, with Oregon considering a ban on lead ammunition.
