45Fan,
I've never tried cleaning case tumbling media, so I really can't address that question. As for the .890 and under brass, I guess it depends on how much under. 45acp brass is notorious for being shorter than the specified length. I have brass in use right now that measures as short as .884, but I do not use hot loads. I suppose a combination of short brass and a max or near max powder charge could cause pressure problems with bullets seated to normal depth.-TR
