ok just got off the phone with the IDNR and the official word is 350 Legend is NOT legal at this time. The law enforcement dept has tested and found that some of the ammo is slightly under SAAMI spec. IDNR have been in contact with Winchester and the IDNR said they will make an official ruling soon. Ironically, the automated chat software on the IDNR website still says 350 is legal. They are going to correct that. So, I guess we wait and see for 2019 season.
