Re: how do u tell scope no good
^^^ good advise.
along with the advice hansom gave you beth, after you have that scope mounted properly, if you have taken the windage and elevation adjs. all the way one way or the other, you need to get them back.
One way I would suggest, take them both (windage & elevation) all the way in one direction till you run out of adjustment.
Then, take them "both" the other way and count the "clicks" very carefully and write it down!
Now take both, windage and elevation and take them both back 1/2 the number of clicks that you took them to.
That should get you close and sart the Zeroing process.
Two Words; "Simple Man", song by Charlie Daniels sums up my thoughts on a "few things"!
