I'm really fussy about my brass and the prep. I've tried several methods from case spinning with Brasso to wet tumbling with pins. I do like the way the wet process cleans the inside and outside, doubt the inside cleanliness has any effect. It does also help the primer pocket cleaning although, the pins getting lodged inside can be dangerous at worst and disconcerting at best. That being said, I recently converted over to the "chips" vs pins and that helps the case clogging problem especially with the smaller cases, 224 Valkyrie in my case. My only problem with my Frankfort wet tumbler is the issue of the drum stopping turning when trying to do 338 LM. I still use it but limit the number of cases to less than 50 more like 30. I use a thrift store-bought dehydrator to dry them and caIs shiny brass necessary and does it shoot better? not necessarily but as a former soldier, I have a thing about shiny brass. I think clean brass helps alleviate damage to dies. Just my 2 cents worth, more like a halfpenny due to inflation.
