In the EASA website they write 2000NM (3700 km) with a 6tons payload for the C295.
In Wikipedia, but I do not know if the data are correct there, it is reported:

Where's the catch? Is it just a better aircraft or are the data a bit "engineered"?
It is intended to replace an existing type with existing performance levels and they made it as such.
If it was competing with the C-295 it would win, despite the latters better specs simply because it is sanction proof, which the C-295 is not.
Of course, that is the importance of having a local production. I was just wandering what they have traded to get better range and payload for a otherwise quite similarly sized aircrafts, and what the russian have instead decide to optimise. E.g, some overload capabilities or a different flight envelope.. etc.
Unless, it is instead a problem of design, as the experience with this size and class of aircrafts was before only in Antonov and Russian engineers have to relearn it the hard way
