Yes!Just about the same as everyone else here...I will add that before I seat my bullets, I brush the inside of the necks with a nylon brush.
Good luck everyone!
I do the same except I dry tumble right after annealing then sizeDitch the wet tumbler. It’s not doing you any favors.
Decap
Clean pocket and wipe off neck.
Anneal
Lube and size
Mandrel
Trim if needed.
Chamfer and deburr.
30-60 minutes in corn cob.
Knock the dust off and check the flash hole.
Load them up.
That looks like brass shot out of an AR15 with a suppressor attached. Not typical of how dirty brass gets shot out of a bolt action rifle in my opinion. My brass never gets that ugly!I would argue there are certain situations that require a wet tumbler or serious chemical bath. Vibrating with corn cob, nut shell, or rice isn't going to cut it without extended time. I can always remediate some of the negatives later in the process through annealing, case mouth prep and dry tumbling.
View attachment 1644467 Here is an example of "Dirty". Ignore the other glaring issues that brass displays (not my rifle). These are cases that I picked up at range and tossed in recycling bin.
100% spot on!…Ditch the wet tumbler. It’s not doing you any favors.

As mentioned before, I'd suggest you make your last brass prep step the trimming, then chamfer and deburr. This will give you the most consistent case OAL. When you FL size a case, that neck gets elongated quite a lot and not in a consistent way. So trimming before sizing is not really the desirable approach.

I chamfer before siziing because little high points/tiny burrs can break of of the edge of the neck and get dragged down the side of the case. After sizing trim to length. I have had brass particles get pulled off the neck edge and create galling that attached brass to the die walls. This only happened to me once with 1 die and many years of reloading. Like someone else said sizing may make the case longer. So trim after sizing.

Some guys try to neck turn to a 10 thou thickness variation. The neck thickness changes after each firing negating accurate turning. If you turn a neck fire the case several times then run your turner with the same adjustment on the necks you would be surprised how much brass is removed and where it's removed.
If you've chamfered before firing, you're saying "little high point/tiny burrs" form after firing at the bottom of the chamfer that can break off?I chamfer before siziing because little high points/tiny burrs can break of of the edge of the neck and get bragged down the side of the case.

This has not exactly been my experience. The only thickness I've found changing is just above the neck-shoulder junction (the donut area). For example, after 16 firings on my Lapua 6.5 PRC brass, that donut thickness there grew by ~.0025 (as measured with pin gauges) and the rest of the neck remained at the .014" thickness that I originally turned them to (no brass shavings until I get down to the donut upon turning one of the casesSome guys try to neck turn to a 10 thou thickness variation.
