Not having a tumbler right now is driving me nuts. I want to finish prepping this batch of brass, but most of it is rather dirty. I'm about to start hand polishing them individually. UGH.
Make it easy on yourself and just load those dull brass. It doesn't make a whit as far as safety or accuracy. Just wipe them off with a dry cotton rag after sizing them to get the lube off. The polish is like a woman making up her face. Its all for looks.

On your other query. Once fired brass is seldom in need of any trimming. If it worked the first time it will work again. I have loaded thousands of 222 brass and never trimmed a one. If I thought they were getting long, I would size them then put a few in the rifle and close the bolt. If they didn't hit bottom, I would load them. If they did it was the trash can. They would take a lot of use before getting too long. They were at the end of their road by then any way.

The reason for checking the length is to insure they don't hit bottom and cause a problem in getting the bolt shut. There are no doubt variations in rifles on where that point will be. That is why there is a standard set of published dimensions. My calipers for many years was a once fired brass that I used to compare length with by holding it next to the one in question. Not very scientific? But it worked.

The seating depth is more important than the case length, but that will be the same regardless if your cases vary .010 in length. In the dies the seating length is established by the distance from the shell holder to the punch.


So what if your brass are .005 short? That isn't going to matter either. You don't need a crimp on those, so a little variation won't matter.

IMO
