I simply see no reason to shoot expandables. Just one more mechanical piece of equipment that can fail. Some people have used them with very good results on all sizes of game, in fact I read an article recently by Chuck Adams stating he used some form of Mechanical broadhead on all five animals he killed the previous year, and I think we can rest assured old Chuck has got enough experience with game and archery to know what he should or shouldn't use. For me however, a well tuned bow and good form and lots of practice makes using mechanicals simply an exercise I don't need. Mechanicals in my book are predominantly used by people who don't take the time needed to get consistent broadhead flight with a fixed blade broadhead. They simply are not something I would risk an animals life on when using a fixed blade takes the "opening up" failure out of the question.
