The mess occurs when you pull that rubber plug and turn the tumbler on to drain it.I feel I would prefer to have dry cases. And as long as it cleans well enough for the rounds to chamber properly that's good for me. I don't care how shiny they are.. I ordered some fine grain walnut. Thanks for the info. If I have to I will glue some plastic over the holes..... As of right now I don't see any gaps between the secondary bowl and the main bowl so it doesn't appear that it will make a mess but I guess I'll find out lol
I also taped over that rubber plug as it would fall out while it was running, putting media everywhere.
It's not about shiny but clean for sure, but this type of tumbling will NOT clean the primer pockets or the insides of any caliber case.
Post back after you have tried it!
