Abstract
An archery practice field tip and related method of use is provided, where the field tip has a first shape that is structurally different from a second shape of an actual hunting broadhead, but where the tip mimics the aerodynamics and flight characteristics of the hunting broadhead. The practice tip can be void of sharpened cutting edges, and can include a head on drag promoting element and/or a crosswind drag promoting element, either of which can be scoops, flanges, fins, holes and the like. The tip can have a head on aerodynamic drag that is within 40%, within 25%, within 10% and/or within 5% of the first head on aerodynamic drag of the hunting broadhead. The practice tip can have a crosswind aerodynamic drag that is within 40%, within 25%, within 10% and/or within 5% of the crosswind aerodynamic drag of the hunting broadhead.
