A lot of people ask me what is parallax in rifle scope and how it will effect the shooting. This effect can cause the shifting of the point of impact at long ranges and can make your apparent group size a lot larger. It is simple to understand, but not that simple to explain without live example. Today I want to share with you a best video that I found about rifle scope parallax. This video is just 2 minutes long and you’ll witness parallax effect yourself.
