The C.O.A.L. for mine is 2.862. I backed it off .006 for now. Today was only the 3rd time to shoot it and first time for a serious session, it did great tho. I concentrated on shooting groups at 200yrd mainly, best was around 1/4-3/8. Best I can do with the scope I have now. The range by my house only has 300 max anyway, so I dont know how it would do WAY out there. I was able to hit some clays I hung up at 300yrd dead center without busting em. I think its a shooter.
