RE: Missed deer.....is broad head still good???
What brand is it?
Make sure it still spins true.
If it is a fixed head and has replaceable blades then just swith them out and you' ll be find. If it is a mechanical with an aluminum body, inspect it closely because it' s probably toast.
If your unsure of it' s integrity, put it away as a practice head only.
Those are my 2 cents.
