[QUOTE="el matador, post: 1121217, member: 12193"] It's not very complex geometry here. The error will be the same whether you're using hash marks on your reticle or dialing for elevation. There is a small amount of error in my numbers due to sight-in distance and scope height, but I wasn't looking for a precise solution. I was only trying to show the magnitude of error that is introduced when the scope is canted. For exact windage and elevation error you need to know the divergence of the bullet from the center line of the barrel, which could be obtained from time of flight. The Cliff Notes version is: The scope reticle is by far the most important thing to level. [/QUOTE]
