Do you think there is degrees in the effectiveness of a double lung?
Do you think one part of the lungs would prove more fatal than the other. For instance, broad side deer, do you think it matters much where exactly you hit the lungs, ie front of lungs, back of lungs, middle ect. To me it seems I have had shorter trails when the animal is hit more towards the front of the lungs ( you know down in the pocket ) than the back, even though it was a double lung and the animal died, he still went further due to placement hitting the rear part of the lungs. I feel that you have a better blood trail and the lungs fill up with blood quicker if the shot is closer to the heart and arteries.
Does this make any sence?
