One guy is about 150 can on his absolute best day do one rep with 300.
Another is a guy calld Tomas, he is only about 185 lbs though he reps 355x3
My friend Dan is about 80kg but he benched 160kg, he is now heavier.
Another guy in my gym is about the same.
All these guys have been training for years. I do not know any 250lb guys who can bench 500. I can barely do 400 and I am 250ish.
