  • Patent number: 9574845
    Abstract: A gun for propelling a projectile, such as a scent compound enclosed in an spherical shell, into a hunting environment comprises a frame housing a compressed gas reservoir in fluid communication with a trigger valve that is operatively associated with a manually-actuable trigger to momentarily open the trigger valve. A projectile barrel and a sound barrel are each in fluid communication with the compressed gas reservoir when the trigger valve is open. The sound barrel includes a pneumatic game call. The pneumatic game call is selectively removable from the sound barrel and replaceable with at least one other pneumatic game call that produces a different game call. A distal end of the projectile barrel preferably includes a plurality of scoring blades fixed therewithin, such that upon exiting the projectile barrel the shell of the projectile is scored by the scoring blades.
