Just installed a new Nikon Rimfire ll 3x9x40 BDC? How can you tell if the scope is wandering. I boresighed the scope on my 10/22, dead center. When I shot it, it was was about 10" high, and, about that much to the left. When I checked it with the bore sight after I sort of got sighted in, it's 5" high and 2" left on the boresight recticle. This was a new rifle with a cpc bolt tune up and a trigger rework with 2.5 lb pull. Don't think I pulled it that bad. Tku
