Great to see states catching on to this. AK has something similar now, referred to as the Alaska Copper Ammo challenge, as does AZ. All reimburse hunters for shooting lead free.
I've been shooting exclusively copper for almost a decade and have had universally excellent results with handloads and factory. One of the big complaints used to be that copper ammo was more expensive, but with post COVID inflation there's really not much of a difference between the cost of quality bonded hunting ammo and copper. With programs like these, the average "half a box a year" hunter would probably actually save a few bucks by going lead free.
