i seen that headshot on tom mirandas encylcopedia video. utterly amazing period. the arrow went hay wire. had to hit a branch or something it went WAY off course and flight was TERRIBLE.

that is by far not where you want to put an arrow on a big game animal. that guy simply got lucky.

good luck with your bowhunting...i couldnt imagine shooting chipmunks. small, quick, and even if you hit them, what will stop your arrow if the ground doesnt? be safe...
