Hey guys,
Many months ago I authored and posted an article on my web site discussing case cleaning with ultrasonic versus a tumbler with ceramic media. I just a added a detail discussion on using stainless steel pins in a tumbler. It worked great and is the method I will be using from now on for all BPCR calibers, and also for all my smokeless handgun and rifle calibers. If you’re interested in more details click on the following link.
