Thread: Small target = more accuracy

It's a question of fitting your crosshairs into the aiming mark with a good amount of white or whatever colour around it. Too tight and you can't see what you're doing, specially you can get diffraction deforming the target shape. A lot of thought went into this with aperture foresights sights for smallbore and fullbore shooting. By equalising the white ring around a circular target they can shoot right up to the limit of what the retina can resolve.
