Well, I just have to know how "accurate" my data is. The attached shows a tape where there are two measurements. I feel good about all of them. The setup was identical for each shot. Why any variance? It is just really difficult to "see" that bullet under all conditions.

Edited to say: Sorry, but I don't know how to make it show up without your clicking on it.
