In Idaho and during the regular season you can use centerfire, ML, or oarchery - your choice. During regular season your ML can be scoped and shoot 209 or rifle primers. During Short range Season you can use ML's, shotguns, or archery your choice... the ml can have all the bells and whistles. During ML season, lead bullets - 10/1000 of bore, open sights, pivot hammer, loose powder - 50 cal or greater for elk and .428 caliber or better for deer.
Those are the basic rules for this year - they just changed from what they were for several years, and hopefully they may change again next year.
