[QUOTE="Davew223, post: 1028310, member: 86753"] I would check with [EMAIL="chris@swfa.com"]chris@swfa.com[/EMAIL] , It's his job to know these things and he has taken care of me in the past. As for a simple explanation of the cant issue, keep in mind that your bore axis is pointed "up" to intersect with your optical axis (line of sight). As you rotate your rifle around the optical axis that "up" will follow the rotation so if you have an "x"deg cant to the left, your "up" will be "x"deg to the left so you will be shooting to the left. Along with that, since you have rotated to the left, you don't have as much real "up angle" left so your shots will be a little lower. In 3gun shooting, some of the stages will force you to shoot with the rifle at a 90deg cant, I will back the elevation down so the bore axis and optical axis are parallel with no "up". Then it's just a matter of aiming about 2" left and holding for elevation. I forgot to add that as you move your optic away from the barrel axis, the angle between the line of sight and bore axis will increase for the same "zero." That increase in angle is why cant becomes more of a problem with taller mounts. [/QUOTE]
