In these past few months, I have read about reloading mishaps, firearm malfunctions etc. on this and other forums, which were attributed to brass problems. I have even experienced some myself. In past years we have gotten brass wherever we could find it for hard to get calibers. Once fired was not always so. Primer sizes were mixed, rims damaged, etc.. We made do because times were tough re: components. Now that we are in a time of relative plenty, I am discarding all of my old brass with any infirmities or of questionable origin and replacing it with new. Who knows when the next component drought will hit. A word to the wise.
