There is one other thing that you might be interested in. After reviewing the tape of our shoot, I began to notice that the bullets that landed right usually also landed low, and the bullets that went left usually always landed high. Then it dawned on me that I had read about this before and had just forgot about it in the excitement of the day. It is called the Magnus effect.

GOLLY GoodGrouper - I suggested that's what caused your first shots being on the left. See my post at just a tad low an left
Magnus is more commonly referred to as <font color="red"> Spin Drift
</font> in tactical corners. I've been debating <font color="red"> dean michaelis
</font> one of the worlds leading experts on this topic (and Coriolis effect) at the Biggerhammer.net Barrett and 50 Cal Discussion Forum site
Turns out Dean was right and I was wrong [img]/ubbthreads/images/graemlins/smile.gif[/img]
I was hoping you could shoot your gun due north, then due south ( 2000+ yards ) and measure the Coriolis effect. Normally only artillary worries about Coriolis.
The best info I've found on these topics is the excellent How do bullets fly?
