Does anyone know how much of a difference in POI the marks on the inside of the ghost ring ears make? I shot my 590A1 at 50 yards today using slugs, and it was right on for windage, but they were a bit low. I ran out of slugs so I couldn't actually zero it, but once I got home I did move the ghost ring aperture up one "dash" to move the POI up a bit. Does anyone know how many marks I should move it up to get roughly centered at 50 yards? The manual didn't say.

I was shooting using standard federal rifled slugs. Don't know the weight off the top of my head.

The manual didn't answer my question, I had already checked. I want to know if anyone knows how many inches up or down one whole mark makes at 50 yards.

I remember taking mine out and having to do 6 or so clicks to get it to move up I think a foot or so.

Cool, thanks. I think I did about that many clicks. I will just have to take it out again and shoot it again I think.
