Started at 100 yrds....wasn't hitting paper......moved up to 50 to where it was decent and then went back to 100 yrds. I installed the scope myself and I do not think I got the rings too tight. I was getting to where it was 1 1/2 to 2 inches high at 100 yrds---what I wanted.....but it was to the left 3 1/2 inches or so. I make the adjustment to the RIGHT to bring it over and leave the up/down alone. She shot 3 inches to the RIGHT and 5 INCHES LOW!!!! She was just at 2 inches high....how in God's name did it drop 7 inches!!!! Its a bad scope--DrASUS
