100 to 200 at a time. My storage boxes are all 100 cartridges so convenient to do them this way... Also never mix the brass from box to box. What goes into the box is the same that came out of the box. Keep track of number of reloads that way. I only tumble now when I feel the cases need it.
BTW this is with revolver cartridges... Rarely have to load any rifle.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
