Good blood trails result from a lung or double lung hit. Blood is sprayingto the side, through the entrance and/or eixt woundsfrom the bellows action of the lungs A heart hit will sometimes give a good blood trail but a lot of time the blood stays in the body cavity. Last deer I shot with a Slick didn't go very far and there was little blood even though the arrow passed through It was a solid heart shot and the blood was all in the body cavity. Had same thing happen with an elk, heart was toast, nice exit hole for the bullet and little blood on the outside.

It's not the broadhead faiing to do it's job!
