[QUOTE="An Idahoan, post: 1892536, member: 95631"] J E Custom, I get what you're saying. It is a problem with an easy solution. Instead of making the bore axis and optical axis converge at your zero (scenario 3b), make the bore axis parallel to the optical axis (scenario 3a). If you have a 10 degree left cant, then at 100 yards (or 200 yards), adjust for a bullet impact of 0.30" left of hold. The result will be that the lateral (or horizontal) separation between the bore and optical axes at the rifle is a constant 0.30" from 0 through infinity. If 0.30" at all ranges is unworkable, then I suppose you'd better make sure that your scope reticle and bore are on the same plumb. Just as long as people are making an informed decision and are not led to believe that scenarios 3a and 3b as outlined above have the same disastrous results are will occur in scenario 2 outlined above.
