Noticed the following page: http://www.accurateshooter.com/optics/canting-effect-on-point-of-impact/ With due respect its creator, it's bad information as the bullet's drop from maximum ordinate is used. Canting the rifle causes bullet impact to shift to the side equal to bullet drop at target range multiplied by the sine of the cant angle. It'll be below the horizontal equal to bullet drop at target range multiplied by the cosine of the cant angle, then that subtracted from bullet drop. Bullets drop the same distance from the line of fire above the aiming point regardless of how the rifle is canted. Maximum ordinate (MO, high point of trajectory above LOS) for zero cant is almost 30 inches at 350 yards for a 600 yard zero for the bullet used to calculate data for. Note the drop below horizontal below the red line for different degrees of cant. As the sine of 30° is .5, note the 30° cant moves the bullet impact half of 100 inches; it's 50 inches to the right and several inches low. And those 5 bullet holes' plotted arc is the same arc as the clock face has at its edge.
