Yeah that probably was a bad pack of muzzy' s i have heard good things from people who use them. And i also was not trying to start a blasting post just wondered what others have had trouble with. I am sure in the wrong circumstance that all broadheads will fail. But like the one post that atlas said he did investigate and could find no reasonable explaination for the failure. To me this is worth more than the one twenty yard recovery somebody gets and then swears by that broadhead forever. I also am waiting for some bad press on the thunderheads wich i have had no problems with actually have had them stay together when i did not expect them too.
