I am a bit worn out this evening; however I have THE hypothetical question of the year to post. You may or may not be aware of this, however as the light enters into the first lens of the scope and continues on through approximately 10 more, the light rays bend, just like they do when light rays hit a prism or water. This principle affect of light causes bullet impact to shift throughout the day. Hence, the wandering Zero. When the sun is behind you, the bullet will impact a little low; to the right and it will impact a little left, left and the poi will be a little right. This is because of the bending of the light rays as it passes through the lenses of the scope. The question? Does a larger objective and erector tube (larger lenses) magnify or reduce this affect?
