Once upon a time (back when targets were not real big and not real close), my bride and I found ourselves on a posse with a young couple, both very new to the shooting game. This was a monthly match in northern California at a well established club and, IIRC, there were five or six posses. After the safety briefing, this particular match was announced as a "no-miss match". If you missed something, you were expected to keep reloading whatever gun you were shooting until you completed a clean string. Three pistol misses = three pistol reloads, etc., not optional. There were several memorable moments from that match. For one thing, it took forever. Two, it was a spotter's nightmare. Oh yeah, the young lady had a bunch of misses, reloaded to have a bunch more misses, spent much of the day in tears and we never did see the two of them at another match.
So...that was a bad idea.
As far as an option to make up a rifle/pistol miss?
Are you relying on one spotter to tell you about it? Or do you need two of three to agree? Or just the timer operator. Or...
Not a fan of the idea.
