Sighting in Target - Black Circle w/ grid lines

[tul9033]

I got a target, I thought from here. It is a black circle with grid lines. I can't seem to find the thread anywhere. It was a print off target with MOA adjustments and 8,9,10 circles.
Anyone know what I am talking about?

This is the target, I have it printed but not saved.
Works great for sighting in a RDS.
Thanks
