I would call that more of Russian Roulette than a mistake. If you can't find your notes, don't assume anything. No offence but guessing a recipe is in itself a recipe for disaster especially if you reload multiple calibers.
Which is why I waited to find my test targets. My ultimatum was almost expired at which time I would have taken them apart anyways and went back to the drawing board. I'm special.....but I'm not completely out to lunch.
Update: Came in to warm up, one of my rounds that I disassembled had no powder in it at all. Oops
