[QUOTE="JustMe2, post: 2503160, member: 42494"] In a previous thread, a forum member stated he intentionally sighted in his scope to hit the target to the left of the 100yd bullseye to compensate for spin drift and Coriolis at longer ranges. Question: what are your views about using a tall target to mount your scope with an intentional calibrated cant and not level? Procedure: Draw 2 lines on a tall target, one line being straight up/down level like is normally done, then draw a 2nd line in a "V" shape to the left originating at the 100 yd zero. As the 2nd line is drawn upward from the 100 yd zero, it should get further and further away from the level line. The result being at the 1500 yd point on the target the "V" line would be maybe 3-10" to the left of the center/level line. Now place the rifle level in a vise and zeroed/sighted-in at the tall target placed at 100 yds. Next, loosen the scope and cant it, keeping the rifle level, to align the scope reticle with the "V" line and not the level line. This would put an intentional ballistically calculated cant in the scope to compensate for your rifle's spin drift and Coriolis as you dial the scope upwards. Now during a hunting situation, you'd only have to compensate for wind holds and not worry about adding spin drift or Coriolis. So, what are your opinions of putting an intentional cant in your scope while mounting it? [/QUOTE]
