All that hair on the bottoms is really cool. No doubt that buck was still growing! Your close on Crossover. On Mongo, you gotta remember, his head and body and ears are all quite a bit larger than bucks in New Mexico or Arizona.
What magazine are you planning on putting an article in? I'll get it for sure.
As for scoring...it depends. If the bump sticks out an inch or so like the tip of a pen then the scorer will probably go above or below it. If the bump looks like a golf ball then it will probably be included. It's kind of a judgment call. I know B&C would prefer most bumps to be scored around rather than over, but if the bump is big enough it'll be included. Also, if the bump is only on one side of the horn it doesn't matter as far as B&C is concerned, because the small measurements for each side are the ones that are doubled for the final score.
