From comments I've read about tumbling finished ammo combined with other things concerning deactivated primers, I never vibrate loaded ammo. As the previous person stated it may be safer to vibrate ammo than tumble it, but why take risks unnecessarly. Vibrating the ammo at this point may be the fastest way, but try to vibrate only as long as mecessary.
I always vibrate my rifle brass first, lube it and size in on a single stage press, then vibrate it again to remove the lube. At this point I check the case length and do any case prep necessary. Now I feel ready to load 223 on the Dillon. It adds a step or 2 but I feel confidant of the quality of the ammo produced this way.
