I shot a 4 pointer last year with strikers and had very little blood for the first 30 yards or so then it got better and better. He went 80 yards on a double lung hit. These are so sharp the arrow went through the deer and buried allmost up to the fletching in the ground! I mean you have to be extra carefull around em they are like a scalpel. It was kind of hard to find the blood cause the ferns were really high and lots of blueberry shrubs and maple leaves. He died within about 20 seconds from where I heard him crashand then found him.
