[QUOTE="Dave King, post: 82486, member: 3"] This last Friday I got smarter, again!! (Many folks would say this is a daily event for me.. [img]/ubbthreads/images/graemlins/smile.gif[/img]) While I was leveling my rifle to mounting a new scope it came to me that I normally performed this task on a level surface... Okay that's confusing so let's talk X, Y and Z axes. The X axis would be the one determining of the rifle is canted (corresponding to the horizontal reticle line in the scope) around the Z axis (a line running straight through the centerline of the scope (line-of-sight line)) and the Y axis would be a line corresponding to the vertical reticle line. Back to the discovery... When I mounted my anti-cant level I checked the rifle level on the X axis BUT FAILED to ensure the anti-cant level was perpendicular (90 degrees offset) to the Z axis. SOooo on Friday I mounted the new scope but immediately noticed that if I checked the rifle level (un-canted) on an inclined rifle target (changing the Z axis away from -0-) I WAS FORCED to induce cant to keep the installed bubble level indicating -| O |- level. Soooo, now I'm on a quest to not only level the anti-cant devices on the X axis but to also ensure they're perpendicular to the Z axis. This should allow me to get an accurate X axis level indication for inclinded fire events. voilà [/QUOTE]
