Just seen this area and seen a topic on cleaning brass. For you guys that are using SS pins for cleaning your brass, take a look at the SS chips. I've used pins for 2 years plus now and just tried the chips and I'm never going back to pins. No stuck media in flash holes, no packed media in 223 cases, and much faster cleaning rates.
This guy Ryan Fannin has the chips. Here is his Facebook site. He doesn't have a website yet, but the chips work great. Thought I would pass along some new information out there for you SS Pin guys and maybe Gals.
I separate the chips from the brass with a RCBS media separator too and that works very well.
