.223 Rem max length 1.760", recommend trim-to length 1.750"

You should read at least one manual before starting reloading, especially the general advice section. Will keep you out of trouble when handling powder and primers along with lots of other good background advice.

Lee makes a very good case trimmer arrangement.

Get a reloading manual.
It will answer questions like this for any caliber you intend to reload.

I would strongly advise against trying to learn to reload without at least one reloading manual!

I'm pretty new to bottleneck reloading too. So someone correct me if this is bad advice.

Also look into a case gauge. It will replicate chamber. It checks all the dimensions together. I caught 2 cases that had bad rims with it. The context of this is I want to create cases that will chamber in any .223 or 5.56 AR that is in spec.

You trim after you size so you need the die to get started. I've had to remind myself of that more than once. Write down your steps on paper to get a better idea of the flow. I will also help you remember things like Lube, De-bur etc.

I also took someones advice - which turned out to be really great advice. Do not try to start reloading with range pick up brass. Buy at least 100 new pieces of brass. This was AR/.223 specific advice. You can extend that to other bottleneck rifle cases to an extent.

Later,
