I my self have side locks with and with out scopes. My inlines are scoped as would be my smokeless if I owned one.
As far as I am conserened smoke less was the first substute for black powder and shooting BH209 isn't much different.
I do know that if the divison keeps up that some day all hunting with any thing but a rock or sharp stick will end the season. My Michigan was smart enough to name muzzle loading season. The antis will use the divison to take all we have today and use the center fire people againest the muzzle loading people. They will use the bow hunters againest us all till all that is left is a season where you can only hunt with a 15 pound rock or a straight sharp stick that weighs at least 10 pound for throwing.
I feel any legal method of hunting is fine. If you don't like one of your hunting partners method of hunting then find a new partner that conforms to your thinking. Then
defend all hunting rights with your life.
Peep sites are great for tired old eyes. Thats how I am able to shoot my hawkins today and not kill the neighbours horse.
