[QUOTE="Bart B, post: 110292, member: 5302"] Good link Brass Bender. Too bad it doesn't tell folks that reticules in the first focal plane don't stay centered when adjustments are made if the reticule is moved separate from the erector tube. Some rifles have their scopes mounted so far off parallel to the bullet's initial trajectory that they are way off towards the edge in the field of view. One has to mount such installed front focal plane reticule scopes such that they can be boresighted to a bit below bore axis by moving the mounts. Otherwise, the off-center reticule is a way of life. If the reticule in a front plane installation is mounted in the erector tube, then it will stay centered because it stays in the center of the scope's optical axis. [/QUOTE]
