How accurate are angle cosine indicators? I remember one of my sniper courses covered this and we only used angle cosines for short ranging out around 300 yards max. If the shots were over 300 yards, the angle cosine weren’t very accurate as they only told you the angle distance, but it doesn’t take into account the time of flight of bullet and the additional drop the bullet experienced. It’s been a long time since that training and living and shooting in Texas we don’t really have angle shots. Not many big hills here. Anyone’s thoughts on the subject?
