Jim I agree that a scope has no advantage over the tang sights, for what I see anyway except it lets you see the target again.
I been trying to use a scope since 08 when my first floater developed in the center of my shooting eye and since then I had another show up that looks like a tadpole. I wok up in the camper one night and looked up at the hatch in the ceiling and all I could see was black with a red ring when I moved the focus off to the side and saw the moon light starting to show up and switching back the light was gone. I thought the retina tore loose so I went to Miles City Mt and had my eyes checked and the doc told me it was advisable not to shoot. Well I packed up at the Baker shoot and went home and had ny eyes checked again and he said there is a large floater tree loose and that was the red ring your seeing.
Well now when I look at the white spot on the gong targets I see two spots

and looking at a black bull I see it barely if the light is good.
I get that gray out you mentioned and shooting at Harris last fall was the final straw for me using the tang sights for paper matches. I guess the 81 years are catching up with me but I will do what I have to to keep shooting the matches even if I shoot just 50%.
I think I will just have to find a place where I can shoot long maybe a power line cut through the trees in a National Forrest or over a corn field and learn how to use a scoped rifle. But there is no clear spots around here where there are no buildings within rifle range to do that.
I know that if my rifle will shoot sub MOA at 200 it will hold 2MOA with the right load at the 1K.
My .50 did it and also the .45-90 did it so will the .44-77 do it.
