I did a simple test with my Burris Landmark 15x - 45x spotting scope
today. The target was lettering on a neighbor's boatlift at a
paced-off distance of 100 yards plus.

I could easily (no strain at all) make out letters that are .300 high
with .078" strokes -- as in the width of an I or the stem of a T.
I could read with "eye test" facility (read the smallest line you can
see) characters that were .187 high with .045" strokes. I could
easily discern individual blades of grass at the shore end of the
dock.

I would think that it would be very easy with this $200 scope to see
holes punched with a .22 in paper targets at 100 yards.

Light was good mid-afternoon light.
