I can't imagine going all shotgun. As I understand it in talking to a CO years ago, shotgun-only mostly has to do with population concentrations and open spaces and limitting how far a projectile can travel. I've been deer hunting since 1964 and the boundries have moved very little if you look at the overall state. There's always seems to be someone talking about something just to get people all wound up.
BTW, I would LOVE to see firearm opener moved at least a week later, more like it was in the "good old days". Keep muzzleloader where it is and just transition from firearm right into muzzleloader.
