[QUOTE="MontanaRifleman, post: 862786, member: 11717"] In you're example the bore is the zero point so it doesn't apply to zero points down range at a 100, 200 or 300. If zero'd @ 200, with rifle already canted to correct for spin drift, the bullet's POI and POA will be the same although the plain of the bullet's and the sightline will be different.... they meet at the zero point and from there diverge. The distance that happens at will detrmine how much they diverge down range along with the amount of cant. If you canted the rifle over 90* with the scope to the side, your windage and elevation reticles switch roles. You can still zero to 100 or 200 yds but past that, the bullet will diverge left or right of line of sight because the scope and bore are not in the same vertical plain. It is an extreme example of what I said above. Remember, to zero a rifle is to align the the POI and POA to be the same at a given point. If the POI and POA are not the same, the rifle is not zero'd.
