IIRC Isn' t he supposed to be around the 80-100 ton range or something like that, or am I thinking of someone else?

I'd put him around 80.
 
Honestly, even if he could lift 100, I wouldn't list him at class 100, since that usually indicates that they can lift far in excess of 100 tons. Colossus maxes out around 70-100 tons.

We were recently given hard numbers by the Nimrods that put him at 750 tons. His "strength quotient" is 1.5 tons per pound. At 500 pounds in armored form that comes to 750 tons.

Sorry, but we alrady have threads dedicated to his strength.  'Now' isn't different enough to warrant another thread.   
 
Is he class 100? & Just How Strong Is Colossus?
