A standard SKS only holds ten cartridges, so if more than ten shots were fired by the jewelry store owner, he would have likely had to reload. And unless he had a stripper clip handy, that would not have been a very rapid process. Of course he could have installed one of those 30 round magazines. But then the story would have read "twenty to thirty shots fired". I'd say the DUmmies.. I mean the robbers probably got off five, and the merchant got off ten. But I didn't bother to read the story, just working with second hand information and applying my distrust of the media.
