Shooting rule?

[unkated]

Definitely Option 2.

I'd allow "Fire at Target 1 until he drops" (or "Fire at Target 1 until he drops and one more for safety") rather than forcing a set number of shots. In that case, Target 2 cannot be shot at until next round.

IMHO, if you want to track, target and and shoot at multiple targets in the few seconds of a round, that had to have been your intent from the beginning.
