I started reloading shotgun shells at 12 yrs old. I am now 62. From the shotgun shells I advanced to 45acp and I have been reloading ever since - all calibers. I recently read an ad about the stainless tumbling media. Received my order on Friday, and 3 days later, I am still tumbling, drying and retumbling. They are still not ready to load and they do not work as indicated. I am going back to my Lyman red corn cob - it is much more efficient and less time consuming.
