Ya know, I use lee loaders a lot and I'm still torn on the batch method vs the one round all the way method. One thing I like about the "all the way" method is that there really is no danger of missing the powder charge or having a double charge. You are only dealing with that single case and you pretty much KNOW if you just charged it of not and can always look if you got distracted for a bit. As a matter of fact, that's the real danger when reloading... distractions. Most manuals will tell you that you should develop a routine, avoid drinking, smoking or distractions but I think most people read that and it just doesn't register as an important bit of advice. But back to the one round all the way method. I like it because I think I'm less likely to make a mistake and since all the tools are right there handy and there is no changing of dies or putting parts on or parts off of a press it just flows for me. I think it's one of those things that you have to practice a bit and give it a chance for it to feel natural especially if you are used to batch loading with a press.
If you don't like it, you can always go back to the batch method.
