Tumbling media question

I’m using walnut shell media and not very happy with the inside of the brass. I run the tumbler for about 2hrs roughly. Do I need to run it longer? Use different media like sand? Not sure what I’m not doing right. And occasionally a piece of the media will get stuck in the flash hole and need to be pushed out.

I use corncob media. You want beautiful, wet tumble with stainless steel. To be honest, I don't care what the inside of my brass looks like. Yes, get the media out of the flash hole. I check all of my primer flash hole with one of those Lyman primer tools anyway.

20/40 does not pack in primer pocket and corn produces almost none of the fine dust that nut hulls produce.
30 minutes produces all the clean you need.
In fact, simply wiping the case exterior with a rag is all the cleaning you need.
Ignore case interior or primer pocket, unless shooting real black powder. Neither effects performance.
Sorry, but you are worrying about a non-issue.

I have, but probably used the wrong type.

I tried two different types; some kind of black abrasive sand stuff that turned my brass black. Then another abrasive that was sand like and tan colored. It cleaned the brass, but left it with a dull finish.

I just went back to corncob media. If I feel like doing more work to get shiny brass, I will wet tumble with pins.

I need new media and can’t figure out what to get. I have that crappy red died walnut and hate it. I had the green and was ok but never hd enough so I just mixed them. Lately I added a box of 100 1/4” washers in the mix and it made a big difference as in time related and it also helps keep the red build up off the tumbler walls. I may spring for the stainless pins.

Stainless Steel pins with a little dish soap & Lemon Shine & water is amazing on cleaning brass. When you use it for the first time & dump out the water and see it's black, then see your brass your hooked. A vibrator never cleaned the inside of brass as far as I can remember.

Harbor Freight has walnut hulls, 25 lbs for $25. 2 different sizes. The large is what sticks in primer holes.

2 hours is not long enough for walnut hulls, I run mine overnight. About 1/2 cup Chrome polish and 1/2 cup 90% alcohol (used as a thinner) will treat 25 lbs. Helps with dust too. I use a cement mixer to mix it up and then add the brass.

I like wet tumbling personally. I tried dry media when i first started reloading...didn't care for it much.
You can get 5lbs of SS pins & a Harbor Freight double tumbler for under $100. It works pretty good for $60.
