Does that apply to all hits from your attack roll (semi/full auto)? Or only to single-shot weapons?

To one damage dice roll, if I'm remembering correctly. So it would only apply to one weapon hit (though it could be any), similarly if your weapon had more than one damage dice (e.g. 2d10) you could only change the damage on one of those dice.
