I bought a Burris 20x-50mm Landmark Compact this summer...
about $90...don't know about .22 at 100...but it does clearly
show .243 at 100...well enough that you can adjust the scope
at the bench...and not have to keep walking down to target...
I make my own targets...put a black cross on white paper...
I sight-in 2 1/2 - 3 inches high...top of cross is 1 1/2 inches
from intersection...where I hold...works fine.
