Abrégé

An arrow loading guide configured for enabling an archer to correctly load and nock an arrow or bolt using tactical feedback only, i.e., without "watching" the process. The arrow loading guide includes a central bore for receiving at least a portion of a shaft of an arrow or bolt, a plurality of radial slots extending from the central bore, and a pair of opposing slots extending from the central bore and through an exterior surface of the arrow loading guide. Each radial slot is configured for receiving at least a portion of a vane coupled to the shaft of the arrow or bolt. The pair of opposing slots are configured for receiving at least a portion of a bowstring.

Abrégé

A crossbow having an energy storage system configured for storing energy when a bowstring is cocked at full-draw and releasing at least a portion of the stored energy when a trigger is pulled releasing the bowstring. The stored energy is defined by an area under a power-curve or draw-curve of the crossbow. The power-curve is defined by the force required to draw the bowstring from an un-cocked position to the cocked position. Between the un-cocked position and an intermediate position, the force required to draw the bowstring is substantially proportional to the draw distance. Between the intermediate position and the cocked position, the force required to draw the bowstring is substantially constant. When the cocked bowstring is released, at least a portion of the stored energy is transferred in the form of kinetic energy of an arrow or bolt nocked on the cocked bowstring.
