RE: Tainted meat?
I wouldn' t see why the meat would be bad. A few years ago my dad shot a buck that had another hole through it, back and just under the spine(where the innerloins are) The holes weren' t even closed yet, but under the hair you couldn;t even see them before skinning. The meat was fine on that deer.
I' m guessing the gamey smell might just be some of the " rutting" smell from his tarsals that' s just making the whole deer smell. Once you get the skin off him, I bet he' ll smell normal.
