Talked to taxidermist today. He aged the buck using the bottom jaw/teeth chart and said the buck is either 4.5 or 5.5 years old. I guess that explains the body size/neck size. The antlers should have been bigger for the age but regardless I am tickled either way knowing I shot an older mature deer. My second biggest deer (age/body) was a 3.5 year old 8 pointer that is in my avatar. He weighed 146 lbs dressed and he was a semi farm deer. I have killed a lot of 1.5 and 2.5 year old deer but never a 4.5 or 5.5 until now. He saved the jaw/teeth so I can have someone more experienced look at it to tell exactly whether it is in fact 4.5 or 5.5. Will be posting a pic of the progress of my 9 point 2.5 year old I got with the muzzleloader this year at the taxi.
