Tumbler Medium Sticks in Cases. Help?

[dicky r]

Crushed walnut media from pet store or Wal Mart, Dillon case polish w/1-2 capfuls. Never a problem, cases look like new.

Hi

About a year ago, I began using a bit of Nu Finish, a bit of Mineral Spirits (about half a cap full of each) and a cut up dryer sheet in my Lyman Turbo 1200 Tumbler. Immediately I got shinier cases but the medium stuck inside most of the cases and I had to shake, tap, and poke it out of them. My last batch of .38 Special cases had medium full to the top of every case. Annoying.

Anyone know what I'm doing wrong? It never happened in years of tumbling until I added these ingredients.

Thanks in advance.

After the media kept clumping into the cases, instead of throwing in the media, the polish then the cases try the media then the cases and let them tumble for a few minutes or until the dry media gets into the cases then throw in the polish. I've found that the dry media will keep the "wet" media out of the cases pretty much.
