SmythBusters: Tumbling Brass With And Without Pins
67
This video by SmythBusters features Caleb and Steve conducting a direct comparison test to determine if stainless steel pins are necessary when wet tumbling brass for reloading. They use two batches of 5.56 cases, one with pins and one without, to evaluate the effectiveness of the cleaning process. The experiment covers setup, cleaning solution, tumbling, examination of the brass (including primer pockets), and a borescope comparison to assess the results and whether skipping pins impacts the reloading process. The video aims to debunk the myth surrounding the necessity of pins in wet tumbling brass.
