I dunno man check these videos I'm sure he could bench 450x1 solid rep, if you look at the 405 video he does 4-5 solid reps with 405 lbs (184 kgs) and the spotters hands arent touching much. He is one strong motherfucker I am sure he could at least do 450x1 solid. His 315 video is obviously another joke but still he gets it up off the chest for 30 with ease
