Abstract: A projectile entangling device, cartridge and method for entangling an object. The projectile entangling device comprises a bolt slidably engaging within a receiver. A barrel is coupled to the receiver and is adjacent to a chamber. A gas conduit couples a compressed gas container to the bolt. A valve is positioned within the gas conduit. A trigger activates the valve and dispensing a compressed gas from the compressed gas container, through the gas conduit and exits the bolt. A first projectile and a second projectile are positioned within the cartridge. A tether is coupled to the first projectile and the second projectile. The first projectile, the second projectile and the tether are propelled from the cartridge and expelled from the barrel upon the compressed gas exiting the bolt. The tether elongates for distancing the first projectile from the second projectile for defining an expanding projectile and entangling with the object.
