#1 and #4 look to be the same bull to me.
I'd say it's around 272 gross.
as far as growing, bulls are already shedding. They are done growing by mid july. It takes time for antlers to harden and then for them to get the itch to rub them, it doesn't happen over night.
For the most part what you see on 4th of july is what you get, yes they can still grow out their beams or tops slightly but it isn't going to change drastically.
Good luck.
