When you get to Mission 17 you have to bag a doe scoring more the 85 and
a buck from 200 yards. The best way to do this is get the rattling
antlers and some kind of deer scent. The doe is pretty easy to get but
the buck is much more difficult. The best way I have found is be sure
you have the range finder,  go up on the side of a hill as high as you
can get. Use the range finder to make sure you have a good shot at 200
or more yards. Start calling and using the deer scent. It does not take
too long to call a buck into the opening for your shot. The best weapon
I have found for this mission is the 280 rifle and the Hawkeye scope use
x-ray mode for the shot. When  you sight in the gun use the outdoor
range. You can sight it in for longer shots, you can sight it in at 75
yards there. When you take the shot at the buck you have to aim a little
high. It should drop and hit the buck. It takes patients because you
only get one shot and he runs. If you miss start calling again and he
will come back. Good Luck and Good Hunting.
