Rocky, it is 52 degrees here today so I put up my bag target and got out my range finder and measured off 25 yards. I already knew I was right on at 20 yards so I used the main horizontal cross hair and held about 3 inches high, at the top ring of the bullseye and I was just below center so 2 inchs high would be enough at 25 yards. Then I measured off 30 yards and set up my portable shooting bench at 30 yards. I used the first line under the main horizontal on the bullseye and shot cross hair. I was right on one in the bullseye and one touching the edge of it. I only fired two crossbolts at a time because I pulled a Robin Hood at 25 yards and hit the edge of my nock on one of my bolts. Gotta get a new one on Monday. My manual says each line below the main horizontal is abut ten yards further in distance and they were right.
