For your own benefit please give the regulations a read over and if you have any questions feel free to ask.
what you can do is buy a supplemental Anterless White-tailed deer tag which will allow you to take up to two more deer from specific WMU's. 320 is not one of them but if you look it up in the regs there is a fairly large list that it dose apply to including 244 so you may be able to get another one. happy hunting.
you can get both whitetail and mule doe tags only if you are looking for more meat, unfort if you used your gen tag you cannot harvest another buck. good luck and shoot straight
