Honestly, if I had been using and having good results with a Dillon tumbler and it broke, I would just call Dillon. If they help you out, great. If not, get out your credit card. Either way, you are back in business.
And to those that say wet tumbling is a better option. Bull Crap! Unless you have a specific reason to wet tumble. Saying its just as easy, Nope. Saying its not messy, Nope. The truth is, it’s a time-consuming pain in the butt. But if you have a reason to go through the trouble, the results are remarkable. If you just love clean primer pockets, great. If you are like me and anneal your match brass every reloading, it gets pretty crusty looking. With just two hours tumbling and another two hours cleanup, your brass will look like new again.
Again, if you have been happy dry tumbling for years, my advice would be to just get another Dillon tumbler. I have been dry tumbling in my Lyman for as long as I can remember. If It dies, midway will have another one here in no time.
