Windage is a force created on an object by friction when there is relative movement between air and the object. There are two causes of windage: The term can refer to: Aerodynamic streamlining can be used to reduce windage. There is a hydrodynamic effect similar to windage. In firearms parlance, windage refers to the side-to-side adjustment of a s...
