These targets are an excellent way to see how much to move windage and elevation when sighting in a gun. One inch squares are 1 MOA at 100 yards, so if you are hitting one square left at 100, calculating the "clicks" is easy. Double the clicks if you're at 50 etc. Good value if you shoot a lot to get the 100 pack - they charge about half a buck apiece at the range!
Pros: Excellent for sighting in and checking zero
Cons: needs whiter and heavier paper
