We’ve mentioned it in countless episodes prior to this one, but have yet to do a dedicated episode to the optical phenomena that is “parallax”. What is it and how does it affect us when we shoot? Some riflescopes have a “parallax dial” – what does that do? How about red dots and holographic sights that claim to be “parallax free”? When does it really matter and when does it not? We try and cram in all those questions and answers into this quick episode!
