I concur what snuffy said. I will add that a hand priming tool would be a good investment to make. The Lee AutoPrime XR with the shell holder set can be had for under $45 from most places. The other work as well, and cost more. Though I would advise getting one. It makes priming much easier. I have been reloading with one since 2008. I would not want to be without one now. I do not use mine much anymore since I now have Lee Classic Turret press with a primer feed system. Though I do still sometimes use the hand primer for my rifle calibers that I have already sized/decapped, and trimmed, as well as tumbled off the case lube. I do this becasue those rounds get loaded single stage batch style.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
