Here is another, granted he could be going down a bit further, but here stick legs is doing 405 for 20.

and how often does he do 20RM's?
The guy is 6'5 252 and runs a 4.57 40 according to his profile. I'm guessing the majority of his work is done in the low rep ranges for power since hes a tight end in college.
like i said before, the guy that boosts his squat doing the majority of his work in power ranges will look a lot different than the bodybuilder that got to the same strength level by doing sets of 10,12,15 etc
increasing tension for reps over time = a bigger you
