I'll be the first to stick my neck out. I'd say 16", maybe bigger. Kind of hard to judge because his prongs are low, but he's got a lot of horn above the prongs. It's hard to tell from the bottom picture how much he hooks, also. He's got good mass, but I don't think great mass. I would put him between 79 and 82. But that's just a guess. In other words "BOOM".
