These are very useful and effective for sighting in a scope. But, would be even more helpful if the sighting grids had a black dot at the centerpoints. I add 1 stick-on at the grid intersection in each corner (and the center) and then have 5 better defined shooting points on each target.
Pros: Easy to see and use gridlines
Cons: No dots at corner intersections
