Wow, can't believe the grief you are getting about hunting turkey with a rifle. I carry a 30-06 for deer hunting and I would definitely take the opportunity to bag a turkey if it presented itself. My father-in-law did just that with his .270 a few years ago. The bullet exited at the top of the far side breast and took out some meat, but there was still plenty left.

I can't really say where to aim, I guess it depends on how good of a shot your are. I am not the best shot in the world but would probably aim for the lower neck. I figure I would either hit it and kill it outright or have a clean miss.

Good luck.
