Thanks for the great comments guys !
Hunting Kuk,
The antler itself grosses just 158 6/8 (he is old and on the downhill side) he has lost a lot of length, but gained tons of mass and mass does not make up for length. A 400" bull's antlers will wiegh in the 14 to 15 pound range per side. This antler wieghs right at 11 pounds.
If i had the other side he would gross just over 360".
