Also let me say that I am not saying anyone posting here is not properly tuning there bow.
I feel archery hunting as a whole would be better off without expandable broadheads not because they don't have there place but too many archery's that DON'T take the time to properly tune there bow. They see on a package of broadheads the old "flies like Field points" hog wash and they just screw them on and never test them. And most take the packages word for it.
I wish all states would make bowhunter do a qualifying test in order to buy a archery tag. But that is just me and it would be very expensive but you would weed out those that don't take the time to make everything right.
