As with many aspects of firearms ownership, reloading requires caution. The post above by 'Old and grumpy' emhasizes a couple of potential dangers: double charging, and bullet set back/improper over all length. Either one can ruin your day, and maybe send you to the hospital (or morgue), so taking precautions is a wise approach.
I'm not here to tell anyone else how to approach reloading, but there are obvious ways to reduce risk. I try to confirm load data I'm interested in, by checking multiple sources. Avoiding loads listed as near maximum can also lower risk, if such loads suit your needs. Cartridge over all length can and should be checked with calipers, before and after testing bullet crimp. For years I selected propellants that would overflow the case if a double charge occurred. Even reducing distractions can help - I leave the radio and tv off when I'm reloading. And I'm not afraid to go back and check (by pulling bullets if necessary), if I have a doubt about something.
Everyone will have their own approach - I met a guy years ago, who figured the max loads in reloading manuals were written by lawyers worried about liability, so that's what he used as a starting load, working up from there. (He may have been suicidal - his wife, who I had worked with, had just passed.) I've seen too many KABOOM! photos, and wrecked guns in gunsmith shops, to approach things that way myself. But there are lots of folks with more or different experience than I have, so there's always something new to learn, and I really appreciate these reloading threads!
