I hear alot of people bringing up mechanicals not opening. I just wonder how often it occurs or if it happens at all. In my opinion, I can't see how they wouldn't as long as all the blades come in contact with the target.

Not saying the Drury's are some kind of whitetail gods, but I was surprised to read in their book that they wouldn't use any head with a cutting diameter smaller than 1.5 in. They prefer the mechanicals. You have to admit, they must have alot of faith in them considering they hunt for a living, and shoot huge whitetails.
