Well, I just started myself (got the 550B, GREAT machine) and here are a couple of things I suggest.
First, RTFM (Read The Fine Manual). Don't try to load one round without reading ALL the information in the front of the reloading manual.
Second, make sure you understand how things are supposed to work with the loader before you start. It's pretty easy if you know what you're doing.
Third, pull the handle slow and easy till you get a feeling of how much force is required. I had a case that wasn't aligned with the resizing die and I mashed the case mouth because I pulled too hard. A little adjustment and the rest went in fine. But go slow, at least until you know what it should feel like.
Fourth, triple check everything on the first few rounds. Make sure the primers are seating properly. Weigh the first several charges to make sure you're getting consistant metering and the charge weight is right. Check the seating depth. Measure the crimp. After a few rounds, you'll start feeling comfortable that the machine is doing it's job.
Fifth, make sure all the dies are good and tight. My seating die was loose and my OAL was wandering. Since I was checking everything on the first few rounds, I found it after only about 3 rounds.
Sixth, only make up a few rounds at first to check that they function well in your pistol. If you find out they won't feed or chamber correctly or won't cycle the action or won't make power-factor, or whatever, you won't have alot of rounds you can't use.
Hope you enjoy it as much as I do.
