Seized extractor pin on MM AC II

Hi Everyone,

I have a seized extractor pin which I am trying to remove. It's on a MM AC II. Unfortunately one half of the screw head is missing, leaving only a "half moon" shaped piece. The metal appears too hard to drill out and insert a stud extractor or drill the pin out completely.

Any suggestions as to what else to try would be gratefully received.

Regards
