I really like these broadheads. I've only killed one deer with them so far...but it left a heck of a hole. I could actually see the blood gushingout of itsside whenit took off. I proceeded to follow a heavy bloodtrail for about 60 yds. and there layed my buck. Not to be sedistic or anthing, but...I've never seen a deer with so much blood on and around it. I'll definately be using them agian this fall.
