Showed Patrick how to sight in a rifle today.  We did both my SCAR and Remington 700 308.  After they were zeroed at 200 yards I set him up for a long shot at 515 yards.  Incredibly he was putting shots on target!  Bullet drop at that range is about 56 inches for a 308, and there was a slight wind.  Here are some picts of the action.

Thats only about 3 inches from the aim point at 515 yards!
