Okay, you have some steps out of order, at least IMHO.
1. Decap with universal die.
2. Measure four or 5 random pieces of brass and be sure they are not over the max length.
3. If over max length or close to it-say .009-trim to min length and chamfer case mouth inside and out.
4. You can postpone the chamfer pending how much peening you get from SS tumbling.
5. I never mix brass sizes in the tumbler. In the tumbler, some water, brass, purple stuff or dawn, pins, secure both ends, set timer, tumble.
6. I just happen to mix water cleaner brass and tumble with no pins for 20 minutes. I used to shake the container but went to tumble for 20. Dump everything into the tool you use to separate brass from pins. I then rinse the tumbler to remove all dirt. This cleans nearly all the dirt and grime.
7. Into the tumbler go the pins, brass, water, cleaner.
8. Tumble for anywhere from 30 minutes to 2 hours or more.
9. I use a 5-gallon drywall bucket and dump the tumbler contents into the strainer thing and then crank the strainer back and forth until the pins stop falling.
10. I take a goodwill towel (special purchase from them), spread it on the driveway or patio and dump the brass on the towel and spread it around, one layer thick.
11. When the brass is dry I lube the brass, FL size, prime the brass, and place aside. My FL dies have had the decap pin removed.
12. I get my magnet and clean up the pins.
I rarely tumble any brass until I have need of it---meaning--- my loaded stash is one mag from gone. Then I will load the recipe I know results in the most accurate and fastest round until I am out of brass or component...which has not happened since 2010. The reason for this is to keep track of the number of times I reload a given caliber of brass. I have, generally, 400+ pieces of brass for every rifle.
I no longer weigh my brass or bullets. If you are into 400+ yard shooting, you may want to start.
Case prep is, or can be, kind of boring. When working with the clean brass I look for cracks in the mouth, any indications of bulging with my magnums,
any indication of case separation. If I even think I find a crack I tend to go back over everything already done. To break the monotony as soon as I feel I need a break I will stop for the day or at least 3 or 4 hours.
My Browning A-Bolt 30/06 is coming up on its 5th reload cycle and trim #2. The 243 Remington 700 ADL is down to 18 loaded rounds. Both of these have been receiving attention for past month or so. Loading will start o/a Labor day.
