Anybody even seen color change through the years on the same buck?
Yes I have.
That would almost seem to correlate to mineral levels? Mineral levels should effect antler as well as plasma makeup.
I have never noticed a change from year to year to be honest, I really never paid attention. I have seen some ares that had a tendency to have darker antler than other areas though. Seems that would give some credence to the type tree pitch being used, or maybe the mineral content of the browse, or a combination of factors??
