I've made two trips on two Saturdays. First trip,4 down with head shots from CZ Mach II. Second trip 5 down, head shots with the same gun, one with a warble. Two shots were 100 yds, all were DRT. I've got to say that if you were to shoot one other than the head with the Mach II wouldn't be too much to eat. Hunting in western WV along the Ohio River.
