Well, smarter yes, but probably not in the way you were hoping...

You cut it up in half and import one half at a time. One of them will have the faulty record in it, but the other one should import nicely, so now you are 50% there :-)
Cycle, rinse, repeat with the half that contains the faulty record. In the end you should be able to do it in 8 or 9 cycles max, which should be a hell of a lot faster than 300...

Good luck :-)
