Either Wikipedia've got their figures wrong or I have trouble understanding the definitions:
"range fully loaded":
A342: 8000 nm
A343: 7400 nm
A346: 7750 / 7900 nm (depending on engine)
the corresponding figure for the 777 would have to be "max. payload range":
B777-300ER 5500 nm
max range is given as 7930 nm, but that would be with reduced payload
or were you thinking about the 777-200LR which does have a may payload range of 7500 nm, i.e. slightly above the A343 but below A342?
if (and that is more of an IF) "range with max. passengers" is the same as "range fully loaded" and "max. payload range", then even the A330 compares favorably:
A332: 6749 nm
A333: 5669 nm
