Sometimes a shooter will have some sort of death jam, gun breakage, lack of ammunition, or whatever that causes an unfortunate failure to complete the course, which is then scored as shot. In some situations, say, a 32 round course where the shooter has not engaged 8 targets, the RO knows for sure the shooter has earned 8 failure to engage procedurals as well as 8 misses, which means that the shooter's penalties exceed the number of points it is possible to score.
Whenever this happens, I still score the course as shot. Sometimes I get funky looks like I'm just being a dick or I'm wasting everyone's time because we all know it's going to be 0. A DNF is not appropriate in this situation because the shooter attempted the course of fire and put some bulletholes on target. Am I wrong? We can't just mark it 0 -- we have to score everything, and the shooter earns what the shooter earns.
