My father-in-law (his name is Art) just gave me an old Berry's tumbler for cleaning my brass, and I have a few questions about it. It seems pretty solid, and I hope it's worth using. Please view the attached pictures and my questions below.
Art told me I would need to add about a cup of water to the rock media when cleaning each batch of brass. I'm not sure why I'm supposed to add the water and I'm curious as to why I should.
Questions:
-Am I just better off throwing away the rocks and using Lyman media in order to clean my brass?
-Will the Lyman media work with this particular tumbler?
-If I keep the rocks for cleaning, how many cases can I clean per batch? I will be cleaning 9mm and .45 ACP cases.
-Do these rocks wear out over time?
-If I am able to use the Lyman media for cleaning, how many cases can I clean per batch? Again for cleaning 9mm and .45 ACP cases.
Any and all advice is greatly appreciated as I have over 1000 cases of 9mm and .45 ACP ready to clean.
