The 5 inches it shrank could be a few things pope maybe it shrank all of that, maybe it shrank and your score was little diff who knows. I have found that my bucks will shrink 3 to 4 inches over the years. It also has alot to do with were they are kept. Woodstoves or a person that likes it warm in there house all time will not help. It is crazy how much moisture they can loose. I found an 8 pointer that ehd got and he was 168 when he left and 164 when i got him back so your not crazy.
