I agree with 82boy. The last batch of Hornady .223 brass I got. The pocket uniformer tool got stuck in about half the cases. The .223 cases are so small that my hands where cramping up by the time I got done. Also. I use the RCBS hand priming tool. I would never go back to using the press to set primers.
Making sure that primer is seated, is paramount to the reloading process. Duds and hang-fires are dangerous. I've never seen it happen. But lifting the bolt when a hang-fire decides to go off could be catastrophic.
