Yesterday when I was shooting I took out my 12 guage with the rifled slug barrel. It doesn't have a scope and I tell you I had a hard time seeing 100 yards over open sights!! I put my "Seeing" glasses on and managed to hit a 8 inch group.

Any one who shoots under 4 inches @ 100ydswith open sights is a helluva shot in my books. It's a long ways out there without glass.
