Glad to see the issue is resolved... I also tumble in the FART with no pins.
The first time was an accident... I usually had the pins in the drum and dumped the brass on top of them, then mixed it up. Then one time I dumped the brass in while the pins were not in the drum. Once I went to rinse them, I noticed there pins were left out, and that the brass looked pretty much the same.
After that, I figured the pins were not worth the time since I wasn't decapping them, and I didn't care about the inside of the case. I actually think the fouling left on the inside helps the brass not stick to the expander, but that might be my mind trying to justify the laziness of skipping the pins.
To dry, I just use a few old towels after shaking out what I can using the slotted endcap on the drum. Dump them in the first towel, do the old bowling ball polish, dump them on towel 2, do the same, then dump them on towel 3 and leave sit for awhile.
