I have been watching a few testing broadheads going threw some steel barrels on you tube.. The best I have found so far is this one that was shot threw a barrel 5 times. Most on the other tests that I had watched never held up after the first shot.. Anyways for those interested here is the one shot 5 times.. I do not see very much to question on this one..
