I have a friend who bags his limit every year using open iron sights on an O3A3. Scopes are over used and over rated. Just have some patience.
Scopes are a blessing in wide open field hunting of 200+ yards
But you are mostly right. I have taken over 30 deer over the years. Perhaps 2 when I was using a scoped Rifle/shotgun. In forest and brush scopes can be more of a hindrance. I have taken most with slugs in a shotgun with no sights just a front bead. Foster slugs group in the kill zone up to near 100 yards with that Sear Roebuck 12 gauge.
Two with an iron sighted Redhawk .44 magnum revolver at around 50 yds each.
