[QUOTE="7magcreedmoor, post: 1088648, member: 48559"] No matter how good the chronograph, if it is optical and close-spaced, there will be some error. It is very difficult to time precisely the movement from one point to another only a foot or two apart. I use three distances for trajectory validation. If the BC value is reliable (go to Bryan Litz for good BC numbers on most bullets sold today) adjusting the MV works well. If you don't get closely matching drops at both downrange targets, then maybe you want to fine-tune the BC a bit, but I find that Berger's BCs work well enough so that if I lean more heavily on the longest range drop data, the nearer distance will be "close" enough for my target sizes.
