You are dead wrong on that. I have taken out BOTH shoulders on a buck with a Muzzy.Dropped him on his nose. I have gone through the shoulder on others for a kill. I have abuddy that hasblown through shoulders with a fixed blade also.All this on large midwestern deer.Shoot at enough deer and someday it is going to happen. When it does, I would take a smaller fixed blade over any large mechanical EVERY time. I have tried both. Any head through the lungs will kill. Not every head on marginal hits will.IF you ever shoot as many deer as some on this board have, you will stop the snide comments about shot placement, because it will happen to you too.
