Yeah, he is gonna be wider than 18". I would say about 20" outside. As far as his G-1's go, if I am seeing them right, they appear to be around 5" to 6" and his G-2's appear to be in the 8" range and his G-3's in the 7" range. I would guess he would gross in the mid 120" range, he is gonna loose mass after he sheds and his main beams really don't sweep in. He is a heck of a buck!
