Six O'clock has served me very well over the years of competition shooting. That is six o'clock where the blackscoring rings meet the white scoring rings.At 200yds and further you can not see the "x" ring clear enoughfor a defined sight picture, so use the very bottom, sixo'clock, of theblack scoring rings.At 600, 800, and 100yds, this is definitely the only definedsight picture you have.I didn't think I could ever get comfortable with any other technique.
