Pistol only. For 9 it works as long as you don't overload it with too much brass. I have found that more than about two handfuls clogs it up pretty bad and it doesn't work well. For 45 ACP, it is very limited in how much brass you can put in there. All the 45 ACP cases stand up on the plate real quick and block the channels from letting upside down brass come down the tube.
It will jam. Did it several times yesterday while pushing capacity on a standard unmodded Dillon DC motor. Original AC motor in the Dillon feeder is about useless, not enough torque to deal with that many slots full and dragging on the bowl floor.
