Posting #3 had a lot of good info!
Powder measure:
I have had good luck with a lot of powders that have low online rankings for metering like 800x and unique. I run the powder dump station and check at least 5 times to check the weight ranges of powder throws before I start, and periodically check weight every so many rounds. After you run a few rounds in the progressive, you will get used seeing to how full each case is before you set the bullet on the case (I don't use bullet feeders for this safety reason).
Case prep:
I don't do anything to pistol cases except look at it while I'm feeding to my press, and drop anything that looks questionable in the trash.
The rifle cases take time, and you may even consider using a single stage for them. I have had a lot of issues with range brass in my progressive. Also, running 223, you will have a lot of crimped primers wind up in the mix. (9mm and 45 have this issue from time to time as well) You will have to decap and swage the crimp before running them. The Dillon Super Swage is amazing for the crimp removal. I size on single stage, crimp and trim before running them in the progressive to charge, seat and factory crimp.
Range Testing:
Since you are loading light for plinking, then you shouldn't load more than about 10-20 rounds before they are tested. You want to make sure that your loads make it out of the barrel and that your gun will cycle with the selected loads without jamming. I made this mistake once Yup, loaded about 200 9mm rounds and they wouldn't cycle. Luckily they worked in my dad's gun, and I didn't have to pull them.
Good luck with reloading! I have used this hobby to find the true potential of some guns that I didn't think would ever shoot good groups.
