We'll be competing at the 4-H Shooting Sports National Championship this summer at Heartland Public Shooting Park in Grand Island. Can we buy shotshells at the facility? or can non-residents buy local department store ammo without any special permits/licenses (aka Illinois)? Any advice would be welcome. We may also try to participate in the AIM state competition at the end of the week. This will be our first trip to Nebraska and are looking forward to it.
