The other day I was at the farmstore and I was going to return my cva balls that I had a bad experience with and exchange for some others. I tried to return them but the cashier said they do not accept returns on ammunition. All I tried to return was a pack of roundballs, nothing else. So then I said I'll just buy the other balls and just not return the cva balls. I am only 15 and she said I have to be 18 and have a valid FOID card to buy "ammunition" which she considered roundballs as ammunition. I have bought balls at other stores and had no problems just a problem with these. Is there a law that prevents people from buying roundballs if you have no FOID card and am under 15? Thanks
