I dumped a mixed lot of used brass from various calibers and load testing into the tumbler this morning in a fit of cleaning off the reloading bench. I wasn't about to seperate them by how many times they've been loaded, etc. Does everyone meticulously seperate brass by number of loadings? For reference I load 45-70 (trap door levels), 357 (plinkers to mid-upper levels, 38spl (light target loads for wife's 2" S&W), and 45LC at upper 14,000 levels (no John Taffin stuff). I typically inspect brass closely after tumbling when depriming, resizing, crimping, and final inspection. Is there any real pressing reason to keep the used brass seperate other than from the new brass with the load levels and inspection process I go through? Seems like all the record keeping and seperating based on number of times loaded is a waste unless I was pushing the pressure envelope all the time.
