I never shot my SBR at a distance which would make an impossible shot group possible. I shot at 75 ish yards. And also 25 yards.
If I was shooting 100 or 200 yards it wouldnt be the same grouping. For one I have no optic on this and my eyes are not perfect.
So you understand that your "about .700ish" group at 25yds, isn't that at 100 or 200 yes and again isn't 1/4 MOA? Ok good my work is done then.
