This video explains the physics behind firearm sights, specifically how bullet trajectory is affected by gravity and sight offset. It demonstrates that sights are designed to be slightly angled downward relative to the barrel to compensate for bullet drop, allowing for a straight-line sight picture to align with the target. The presenter tests this principle with a pistol at various distances, noting the point of impact deviations.

This podcast episode, originally from 2001, revisits the fundamental physics of bullet trajectory. Tom Gresham explains that a bullet drops from the moment it leaves the muzzle due to gravity, and its apparent upward path is a result of the scope being mounted higher than the barrel, requiring the barrel to aim upward to intersect the line of sight. The discussion also covers how uphill and downhill shooting angles affect bullet impact and the importance of understanding trajectory for accurate shooting.

This video demonstrates the significant impact of angled shots on bullet trajectory, particularly in high-altitude hunting scenarios. Instructor Jeremy Wyers explains that gravity's effect is reduced on angled shots, leading to a higher point of impact if not compensated for. He illustrates this with a 32-degree angle shot at 800 yards, resulting in a 14-inch vertical deflection. The video suggests using angle meters, cosine indicators, or advanced rangefinders like the BR2 with onboard ballistic programs to calculate and apply the necessary corrections for accurate shooting.
