    Thanks for your previous clarification! Here's another puzzler for me:
    Ranging - this part I find unclear, perhaps because of the sight picture diagram published on the XS sights web page (see link below), which suggests moving the POA a few degrees down as the range increases to 25 or more yards. In my reasoning, the only way this is possible is if the sight line is designed to be at a shallow downward angle so that it intersects with the parabolic (hyperbolic?) path that the bullet travels. By this same logic, it should intersect again as the range increases further (50-75 yards?), so that you would bring the POA up again to shoot at even longer ranges. Am I getting warm?
