I tried the SS pins and did not like it, several cases in a batch would have pins wedged sideways in the primer pocket. Also did not like the water and having to let the cases dry. I have gone back to tumbling with media, the current Lyman material I'm useing is a pain as more than 50% of cases have media lodged in the flash hole. I going to get some coarser media to take care of this problem. Also tried Iosso liquid polish and don't like it, I'm going back to Mother's mag wheel polish.
