I personally gave up on depending on tooth wear for age.
IMO, it remains an excellent method for obtaining good trend data, and will typically be correct within 1 year for 2 1/2 to 5 1/2-yr-old bucks. It is less accurate above 5 1/2, and one that we might guess 6 1/2 could really be 8 1/2, whereas a lab should be more likely to peg that correct age of 8 1/2.
Unfortunately, imo, you're more likely to be "way off" using a lab because of human error, when one guy's "mailed in" jaw bone gets confused with another. A few years ago the King Ranch had a collection of bucks (of all ages) which they had been monitoring since fawns, and knew the exact ages of all. They submitted the jaw bones to a lab, and in this case, they received some gross lab errors, and wouldn't have known they were lab errors had it not been the unusual case of their having tracked every one of these bucks for years, from birth to death.
Also, the reason I asked if "TN Joe" was certain this jaw bone was from "his" buck:
I've many times seen people get back a jawbone from a taxidermist and/or a meat processor that was
NOT their deer's jawbone. To insure you're aging "your" deer, you typically have to pull them yourself, or at least witness it, then see that it's immediately labeled and kept up with.
You can always do both to get the best estimate you can on any particular deer's age --- just saying, no method is 100% correct, not even a lab.
But if the above depicted jaw bone in question is sent off to a lab, I'll bet you a donut against a dollar it comes back as a 3 1/2 (or younger).
