According to USCCA it is 86%: Just a moment...

For reference, every gun used in mass shootings shoot one bullet at a time. I have not heard of a mass shooting that utilized a fully automatic firearm.

As a purely technical note and with even some semantics thrown in..........even an automatic military rifle fires only ONE bullet out of the barrel at a time. It fires bullets out of the barrel with ONE TRIGGER PULL for as long as it is pulled or when the magazine runs out of rounds. There may have been some derringer or shotgun with 4 barrels that had some kind of hammer that would strike the primers of all 4 barrels at the same time so that the bullets or shot exited the barrels at the same time - but, I don't know about any - and I can't see any advantage to it. And there would be a disadvantage of more weight.
