Used to think age had alot to do with rack but this year I realized it does not matter. This years shotgun season when I was checking in my deer this kid brings in this nice 13 point buck. As I was getting ready to leave the DNR guy said its a 1 1/2 old buck, the hunter said no way, and I thought the same thing so I stuck around to see the DNR guy show him the teeth. Im not a expert at judging teeth but the DNR said that a deer only has thatthird premolar with three cups when they 1 1/2 years old and the next year they loose it and its replaced with one that has only two cups in it. The DNR said theirs no deciding on wear since they only have that cup at 1 1/2. after that he said you can debate wear on food source and other stuff but not a 1 1/2 year old. He aged mine at 2 1/2 busted rackeight. The next day my nephew gets an eight bigger than mine and sure enough it was 1 1/2. But the 13 point I spoke about had a nice inside of maybe 12" or so and tines were nice, but the mass was real bad maybe at the base only a little bigger then my thumb. The dnr said that is the only way you put age to a rack and that is buy mass but he said thats not always the case.
