estimating 5x5 max help

[tempest2003]

i need some help estimating my 1 rep max. im currently doind 235 on bench for my 5x5 routine, is there a chart around i can look at to calculate my 1 rep max? most charts do not go that high, any help would be appreciated, thanks!

It would be best just to take a max, those charts 'might' be somewhat close or they can be way off. It's basicly relies on what kind of strength you have. Like Needsize can rep 500lbs for 10 on the deadlift and so can I, but me it would put me so out of breath I would almost die lol, but his max is around 600+ when mine is closer to 8.

Reminder he is a bodybuilder and looks way more muscular and I look more like just a football player being a powerlifter.
