It appears that you posted a dead link.
While I have not seen the proposal I think the idea is to expand the pre-unigov ban aganst firing a firearm in the city limits. It is not suppose to affect ranges, only those who want to hunt or shoot on their land in Marion county. Should not affect carrying as that is a state issue.
