Wet tumbling media ?

I'm currently using the pins that came with my FA tumbler. However I'm not impressed with the results particularly, in the primer pockets. I usually load it with approximately 200 or so .308 or 300WM. A squirt of dawn and a half tablespoon of Lemi. It seems the pins aren't aggressive enough in pockets or inside the case, even after 5 hours. What is everyone else using??

Are you using really HOT water?

When I use really HOT water with Dawn and 1/4 tablespoon of LemiShine, then rinse with cool water, where I get pretty good results in less than an hour of tumbling with the pins that came with the tumbler. These days, when I wet tumble, I no longer use pins . . . unless the brass is really cruddy from being ejected into mud or dirt that gets inside the case.
 
I use a Rebel-17 tumbler, 5#s of stainless pins, around 4.5#s brass, 1/4 teaspoon citric acid/Lemishine, 3 good squirts of dawn and hot water. Really nasty stuff gets around 4 hours.

Maybe your pins are too large. I'm using these.

I ordered them back in 2012 from Midway along with a Thumler's Tumbler. The pockets and case interior clean up nicely. I use a squirt of Dawn and a very small amount of Lemishine; only half 9mm case or so. I learned that adding some car wash/wax to the soup eases mouth expanding and sizing of pistol cases.
 
Hot as I can get from the faucet. I've seen chips and little saucers, and some stuff that looks like swarf from a lathe cut. Any of it better?
I tried some stuff called southern shine. It was small chips that made a mess. It would stick to any place that was wet. The dehydrator/dryer would have bits in it and they seemed to keep falling out of cases. Was finding them on the floor no matter how careful I was. I got rid of it because I didnt want a piece of it finding its way into my barrel when fired. I'd recommend just getting some other brand of pins. The pins do wear out or get dull over time and need to be replaced.
 
Never tried that many at a time but 200 pieces of 300WM may not be getting good movement/contact of the pins. I have done 200 223 sized and have good results.
 
I use STM pins and chips from Southern Shine IIRC. I added chips later in life. Only reason chips (or pins) would be falling out of cases after rinse is not submersing the brass (with media still in) into a tub of water ( I used the F/A separator, clam shell with top and bottom tubs. With the brass submerged in the water bath the media easily comes out and falls into the non screen tub of the F/A separator.

STM pins have been in use for 10 years and the chips another 5. Once you find a smart way of doing it and an efficient way you will be happy.

You could also try jewelers media too. those are a little fatter, softer but still have points.

Never been a fan of the F/A pins. I am a believer not all pins are created equal
 
I forgot to mention that the pins will get pretty grimed up. When that happens I do a 2 hour run with hot water and Simple Green. Pins come out shinny again
 
Running cases for hours in a pin tumbler just dings up the case mouths and removes the carbon from inside of the necks. Both of those issues are undesirable to me. I run cases in my STM tumbler for no more than 1/2 hour, so the pockets are not completely cleaned. They are cleaned adequately but some carbon is visible. If I want the pockets 100% clean, I'll just run the pocket uniformer into them. It only takes a few seconds for each case.

I wouldn't expect any method to clean the primer pockets. I use a hand primer pocket cleaning tool. You shouldn't have to tumble much more than a hour.
 
Never have bothered with pins/media just hot water, Dawn, small amount of Lemi-S. Occasionally a light pour of vinegar(I go back and forth on this, shot of lemon juice) rinse with HOT water. I like to sun dry brass. Run 1/2 hr- 1 hr. I have it almost full of water, never had case mouth issues.
 
With the pins and than added the chips I run maybe a hour. The chips cut run time to achieve my desired pocket cleanliness.

And have many a time done just the water and no media as mentioned works great too.

Southern Shine has a Brass Juice solution premixed, it is very good product. And lasts through some batches too. I am a Dawn/Hot water, Leminshine user but the Brass Juice.
 
Hmm, dunno. Maybe I'm adding too much brass, not enough pins? I will say my pins are tiny, maybe 1/4 inch long, and maybe as thick as a mech pencil lead
