It' s stupid to attempt shooting two with the same arrow at the same time. That arrow might go through the first one just fine and usually does. BUT, it has really lost a lot of energy. We have to worry about an animal moving as it is, who wants to worry about two moving. I suspect you' ll get more BAD results than good. AND, the kill zone is not that big. Trying to line up 2 eight inch pie plates 2 or 3 yards apart on targets that move is something only a Byron Ferguson should be trying. I usually don' t tell people what they should consider and not consider an ethical shot but, in this case I' ll make an exception. Dumb idea.
