i spent a few hours sun sighting in my new tc omega and was very suprised how i did with open sights. with christmas coming i could not afford a scope for this season. at 50 yards i was able to repeatedly shoot in a 6 inch circle,and 100 yards was a little bigger but here in ct where i hunt i will probably not shoot over 60 yards. with knowing how accurate new ml are, next season i will have a scope!
