I'm am a relative newcomer to reloading, only starting in August 2012. However, I am anal-retentive about inspecting brass to avoid nasty surprises. Being a scientist (PhD in Organic Chemistry) I have a detail oriented approach to everything I do which has naturally been applied to my reloading. My 3 step brass cleaning procedure (1. tumble walnut, 2. tumble corncob, and 3. ultrasonic bath cleaning) forces me to inspect every casing at least 3 times which has caught every crack, split, and unsightly bulge before the brass ever makes it to my single stage press (plus the brass looks brand new). I have had a couple of cases split during resizing, so you have to be cautious even then. I keep good notes in an Excel workbook on my reloading trials and they have proved invaluable in avoiding repeat mistakes (or even less critical problems, for example I separate 32 ACP brass manufacturers into 3 categories based on brass thickness, the optimum bullet diameter is different for each category, and I have bullet resizing dies to tailor the bullet to each category of casing to give the perfect neck tension). The results of this meticulous approach is 100% chambering and 100% firing for every round I have handloaded so far. That does not mean I have not broken down bad rounds for a number of reasons (like buckled casings during crimping, remember I am a newbie), just that by the time the rounds pass my inspection and make it to a box they are reliable and work flawlessly. I prefer using powder scoops for charge to charge consistency. So, I make my own custom powder scoops using aluminum 25/32/380 casings with a straightened large paperclip wrapped around the base and trimmed down to hold various oddball volumes that I commonly use (like 0.47 cc). All of these things together assure good safe results (the most embarassing thing I have done so far is forget to put a primer in and have the powder dump all over the place through the primer hole). Perhaps it is misplaced confidence, but today I have "more" confidence in my reloads than I do in factory ammunition.
