take it to the 100 yard range on a calmish day
make sure your 100yd zero is spot on. then shoot a box - 5 moa right, up, left, down. if it is tracking correctly you should end up at the start point.
next tape some a4 pages together to create a "tall" target. put a dot on the bottom, shoot at it, then dial up 20 moa and shoot at the dot again, and use a good measureing tape to measure the actual distance. this might also tell you if your scope is mounted at an angle.
make sure you are shooting at EXACTLY 100yards, and shoot off a solid rest to eliminate shooter issues...
let us know the results and we can start trying to figure out what is going on.
