Wet tumble brass cleaning worth the cost? Have been watching videos on the new Frankfort wet tumbler from MidwayUSA for $199. And wondered if any of you used a wet tumbled type cleaning method. Have been using the walnut/corncob type for years but never got the results that I'm seeing on youtube vids. Is it just another toy or a real break through in cleaning brass. This will be used mostly for 223/5.56 brass.
