Source: Webster's dictionaryA certain amount of windage allows the ball to fit down the bore, though the greater the windage the less efficient the propulsion of the ball when the gunpowder is ignited. Source: Internet
A drum-type knob is used for windage adjustment. Source: Internet
Instead, it had a low-profile iron sight adjustable for windage and a Weaver base for mounting a scope, a precursor to the Colt and Picatinny rails. Source: Internet
Other factors that affect range include sea-state, currents, windage and any charge that can be reclaimed while under way, for example by solar panels in full sun. Source: Internet
The rear sight can be adjusted in the field for windage. Source: Internet
This spin, together with the elimination of windage as a result of the tight fit, enabled the gun to achieve greater range and accuracy than existing smooth-bore muzzle-loaders with a smaller powder charge. Source: Internet
