Hi, I am new into optics. Brought several scopes including this Nikon prostaff (4-12x40mm) that I put on the AR15 and try to zero the scope for 25 yds today. I can not even hit the paper. The more I played with elevation and windage, the more messed up it seems. So after researching on the web. I followed these step by step procedures at home
1. Center the scope first using the mirror method as well as counting the clicks from both end and divide the full range (# of clicks) by 2 for both elevation and windage to get the center of the scope.

2. Then I use the laser boresighter (laserlyte) to roughly zero the scope before I go to the range again. I heard this will save time and ammo to get on paper.

I then try to move the cross hair so that it line up with the laser dot on the wall.
Problem I ran into: I ran out of both windage and elevaton range to play with. i.e I can not move the cross hair any further to the RIGHT and DOWN to line up with the laser dot. It max out. See pics below.
Wonder what I did wrong ? Many thanks
( Also tried it on Mueller 8-32 x 44 scope, also ran into the same range issue). I thought by center both scope, it will take care of it. But it did not.
