It's not the broadhead. It's shot placement. You probably had a high lung hit. Was the cavity full of blood when you opened her up? High lung hits tend to give worse blood trails because it takes time for the chest to fill up with blood and spill out.
I had the best blood trail of my life with slick tricks. Take a look. I love posting this link. I do it every chance I get LOL
. Great memories....
