[QUOTE="JBM, post: 73047, member: 1969"] Assuming you meant a 20 moa base, I don't really think it had much to do with it. The barrel is always at an angle to the line of sight. Any angle in the base can be included in that angle giving the same answer. Errors in scope height give an angular error -- so many moa per yard. It's usually pretty small. What were you trying to measure at 100 yards with a chronograph that scope height would have an impact on? That part, I don't understand. I'd be more inclined to suspect the BC you were entering.
