For the record...
As I said in the original post, I don't know all the details. As many have stated, there could be many reasons for something like this to happen...with any brand of shaft.
Also, this wasn't meant to be an anti Carbon Express thread. I don't care what anyone shoots, but what ever you shoot, after seeing those pics you may want to inspect your arrows a little more often.
Bo Hunter, If this ever happens to you (and I hope it doesn't) don't pull the arrow out...let the doctor do it.
