It appears I have to learn things the hard way despite my friends giving me good, solid advice otherwise. I got overly excited about my new 550B and the ability to load my own 9mm ammo. How wonderful, I thought, that all this ammo just started appearing in bins aside my bright and shiny, blue machine. I couldn't help myself. You will imagine my dismay, then, when I discovered yesterday afternoon that I now have 500 rounds of ammo that I will not reliably cycle the slide on my XD. I called a friend of mine, who's been reloading for years and whose brain I did not pick because I thought, "How tough can it be?" and he was not sympathetic. He laughed at me and suggested that after I pull all 500 bullets with my impact bullet-puller that I'd likely not make that mistake again.
