Gents - I guess I'm posting this to share what I found earlier today. I ran a batch of 250 or so, 38 S&W cases, all mixed head stamps, thru the rotary tumbler. After drying, I wanted to sort them, knowing there was some really old ones in the mix. The cases had already been resized prior to cleaning. I knew some were of old vintage balloon head style and I was not going to reload those. While setting aside the WRA Co, REM-UMC (some 38 S&W and 38 Colt NP) and USCCo cases, as well as a few other older ones, I thought I saw a small SS pin in a case. I looked close and found there was a half size pin, wedged in the "balloon head" are of the case head. I then looked at a few others and found several more. In total, about 1/3 of those cases had pins stuck in them. Doubt most here would load cases like that anyway, but if you plan to and utilize a rotary tumbler with pins, may want to check the inside of the brass before loading. I attached a pic to show that most all of the pins were the smaller size. Cheers, Bill in MA
