The mass at the base of his antlers indicates to me that ne's not a1 1/2but the body size and short face say 1 1/2 to me. The oldest buck I've killed there was 3 1/2 and he's pictured in this thread. I've also killed 2 2 1/2 year olds on this property that had noticeably better racks.

Only one way to really tell....I'll have a look at his teeth when I poke a hole in him next year
