I say find a place to hunt and invite him. Then tell him about this huge buck you have been seeing every evening in this one particular spot. Let this go on for a week or to. Put him close to it and tell him all you can kill is a doe!!! Maybe that will open his eyes. But, if you are hunting with him as a guest I say don't shoot.
OR...........
Turn a pack of dogs loose at night and shoot it in the head by spot light...... At no closer that 700 yards.....While it is running....
