Im not going to poke my nose too far into it...but I will say-

Three months isnt much time at all when your trying to get into killing shape. When and if a deer does come out within your effective range, its an entirely different game than putting a pin behind its shoulder. You need to be able to pick a single hair off of that deer, and split that hair. If you can do that in three months, more power too ya...

My two cents, take it for what its worth, and good luck...
