Any brass hull can have its life extended many times over by annealing the mouth. Any method of heating the brass to, say, 500-600F will work. Dipping in molten lead and holding a few seconds is quite good; don't clean the brass first or it is possible to get some soldering. The amount of work hardening the mouth is subjected to determines the frequency of annealing. Something severe like the pie crimp shown would require frequent annealing, whereas a light inward crimp might not need annealing for several loadings. Glue/water glass requires no annealing, of course.
Careful with molten lead. Wear hand, body, and face/eye protection at all times. Be sure the hulls are all completely dry and free of foreign matter, but don't polish off the surface oxide.
