Would like to get some clarification on this from the writers. Under ammo dice rules it says "You can never hit more targets than you have rounds of ammo in the magazine of your weapon" Now for weapons that have a magazine of one and a ROF 1, you can roll one ammo die. Ammo dice have two effects on success, as described in the rules. 1) increasing the damage of your base hit or 2) triggering an additional hit on the same target or hit a secondary target in the same hex.
The way I read the rule is if you have one bullet in the magazine and score a base hit, that is a "hit on a target" now if your ammo die also succeeds to me it makes sense that since you have no more ammo left, you can only trigger the effect 1, but not 2 because that would mean you hit the same target twice with only one round.
Others suggest that "hit more targets" only means you can't trigger an additional hit on a separate target, but can apply an additional base damage hit on the same target.
To me the latter interpretation just gives a random advantage to rolling ammo dice with only a single round in the magazine.
I know how I will interpret it, but it would be nice to have clarification if this is just a phrasing thing and "hit more targets" = "land more hits" or is it meant to be like the second interpretation described above? I'm not really looking for opinions here, just what the intent or vision of the writers was.
Edit: I might have phrased the OP a bit wrong. ROF has essentially nothing to do with this, this situation applies for any weapon that has a single round in the mag left. In that case you can use a maximum of one ammo die (thus the ROF1) the weapon's ROF can be anything, but at that point only one ammo die can be used.
