i mean.. i usually only wet tumble for 60-90 mins (depending on how nasty the brass is) to achieve results that would take overnight in treated walnut...
also hows the primer pockets look with the chips? i know the pins do a knockdown job of it.
I graduated from the HF rock tumbler to the full size Frankford before giving the chips a try, so I can't say how much time the chips save in the HF rock tumbler. I used to deprime and tumble dirty cases, sometimes with a lot of sooting residue on them, for 90 minutes with the pins, depending upon how many cases I had amassed for a load. With the chips, I've dropped back to 60 minutes for a similar load and if I wasn't looking for that NIB clean, I probably could drop back a little more. I don't obsess over the time much so my observation is somewhat laissez-faire. Its good that you mention the primer pockets. The pins did a little better job at 90 minutes than the chips at 60. Not like there's chunks left behind, but definitely not Spic-N-Span. Doesn't affect primer seating depth, just a
small amount of stain left in a star burst pattern around the flash hole. Either way is a horse apiece in terms of clean necks inside (=more consistent tension). I still have my pins but have not tried a duplex load of both to see if one compliments the other. Chips are a little cheaper than pins but considering how long they last, its not a real factor. Either media as you observed bests an overnight shake in walnut media other than the high polish that walnut leaves on the outside.
One caveat. Wet tumbling gets the cases so clean that they tarnish rather quickly in storage. I don't vacuum seal them, preferring instead to store them in cleaned quart JIF jars. Their lids are not airtight by any standard. Never had that with my walnut media. I have around 350) 450b cases sorted by cumulative CHG and how many times they've been reloaded. Some sit for quite a while before getting reloaded, especially since the abundance of new bullets to experiment with has dwindled. Not my go-to caliber for casual plinking.
