I have a Bushnell Trophy 3x9x40 on a Ruger 10/22. I haven't got it all the way sighted in yet. I shot it once before and had it close. I shot it today. I was somewhere between 5-10 yards. That's about all I can shoot here at home. I was just shooting more or less for the heck of it because I figure I will take it somewhere I can shoot farther and use my vise to line it up. However, I noticed today when I adjusted it some that I have ran out of adjustment up. It is hitting around probably 1"-1.5" low. Is this a scope problem or could I be too close to the target or something else.
