Larry Allen benches 43 reps with 225 and his max is 700.
Ronnie Coleman benched 78 reps or so with 225 several years ago at some Met-Rx convention. Who knows what his one rep max is, but is definitely has to be less than 700.
The legendary strongman, Bill Kazmaier supposedly benched 50 reps with 405 (according to out fellow getbigger Onlyme), and his max (Raw) was 661.
The math does not add up
