You can wipe the brass clean with a clean rag, just no grit allowed. Use no ammonia ever.
once you have the brass clean, open your action and drop a piece into the chamber. close the bolt theoretically you are in battery, eject. No binding, no extra muscle required to close or open? Brass length should be good. You have FL sized so take an Accubond and see if it drops into the brass or just sits there, which is the correct state.
I have the Lee trimmer that chucks up to a drill. I had trimmed a case and just wanted to verify its length before I started in on the rest. They ended up at 2.010 which is fine. I'm not going to get too crazy loading them long as I don't want to compromise feeding from the mag.
Now, do you have a chamfer tool? If you have one, now is when you use it(shoulda done this prior to sizing, just my opinion). The squared off edge of the brass may shave some copper off the bullet as it is being seated. I don't like it, probably won't hurt, still don't like it, get an inside and outside chamfer tool, I like Lyman, RCBS, not Lee, and must have a handle.
I have the double-ended RCBS chamfer tool. It seems to work very well.
Do not buy a priming tool, see if your press can stand in for the duty. If you want a priming tool don't get the square Lee. the round one is out of production. RCBS makes one I like even though i am having some troubles.
My RCBS kit came with their priming. I'll give it a shot.
Set your scale up, zero it. pick it up and move it to a different table. Check the zero. This is just to show you Flat is not always flat and you need to always re-zero your scale before you open your powder. An Oversight here can have bad results. Keep your appendages attached and scars to a minimum, please always re-zero.
open your loading Log Book and make an entry. This is just to remind yourself Brass, caliber, bullet, powder, charge, primer, date, temp, anything else you want to add.
I happened to grab a notebook the other day and will be keeping detailed records.
Open your powder, measure a charge based on published data, not internet numbers unless you trust the source. Load powder into brass. Look into the brass and get familiar with what the charge looks like, after ten or so rounds you will know and an over-charge will stand out.
I have several good sources for load development. I have the Nosler hard copy, several powder and bullet manufacturers data websites, Quickload software, and several experienced loaders at work (and you guys) to ping ideas off of.
You'll have a lot of fun and satisfaction in loading your own.
