[QUOTE="Shawn Carlock, post: 58598, member: 4"] No doubt that gravitational variances due to latitude and density will effect bullet flight. I believe that in most cases this effect to be very small,(much like the rotation of the earth causing windage issues when firing north or south). The situation that I have run into has occured at the same location on different trips to the range. With the gravity issue constant, I just can not see any other place to turn other than conditions not read correctly or not read at all. If we can come up with conclusive evidence that a particular effect is causing this zero change in the degree we are seeing, I am all ears. Since I have no way to measure or guage thermal updrafts down range, my ideas will probably remain theory even though I believe them to be correct. This is an interesting topic, I had not thought of gravitational variances until it was mentioned. I look foreward to more info on this one. [img]/ubbthreads/images/graemlins/smile.gif[/img] [/QUOTE]
