Abstract

A projectile shooting guide includes an elongated guide member to be mounted on a bow by a support and in its mounted position the guide member extends towards the bowstring. The shooting guide also includes a device to allow vertical movement of the guide member during a drawing movement of the shooting guide. The guide member is pivotable and in its pivoted position a resilient device urges the guide member to remain pivoted. Projectile loading is accomplished in the preferred embodiment by a moving pivotable portion of the guide member. Other embodiments employ spring, hinged or sliding loading devices. The guide member also includes a bowstring slot extending longitudinally in the guide member which allows drawing and shooting movements of the bowstring. The rearward end of the slot narrows to guide the bowstring to the lateral center of such slot. A projectile is included for use with the shooting guide. Such projectile includes a grooved portion to engage and align with an elongated ridge portion on the guide member.
